royHi. I’m Roy. I’m a web designer and developer located in The Netherlands. My wife and I have two adorable little daughters and two cats. I’ve been a web professional since 1997 and a blogger since 2002. In 2002, I co-authored a book called “Byte-size Flash MX“, which dealt with optimizing Flash files.

I love going to the movies, and I’ve written over a hundred movie reviews on Choking on Popcorn, which I set up with Suzero in 2002. On January 1st, 2008 I quit my job as a Flash developer to focus on WordPress, Flash and freelance web design.

On roytanck.com, I mostly write about technology, gadgets and open source software. This blog is also the home of my WordPress plugins and other projects.

  10. Roy,
    I just discovered your Wp-Cumulus rotatable tag cloud. That is awesome.
    I wonder if we could get it to work on a site and blog that is based on TikiWiki instead of WordPress.
    Any thoughts?


    Comment by Bill Albing — January 27, 2009 @ 9:44 pm

  11. Hi Bill. This site probably has all the documentation you’d need to port Cumulus to TikiWiki. You’re completely welcome to give it a try :). I myself can’t possibly port it to all the other platforms out there, the WP version has been taking up way too much free time already.

    The Flash movie’s interface is really quite simple, so it shouldn’t be too hard to do.

    Comment by Roy — January 28, 2009 @ 9:19 am

  12. Yeah I see… Main’s not loading… (index.php) =) I’m thinking of starting free-theme business.. These designers get so much PageRank, but don’t know what to do with it! Abd I think I know what to do… But haven’t got it.. =)

  15. Hi Roy
    I had a problem with the WP-Cumulus Plugin, it’s working good in my site but the functions of my submenu under the main banner stopped working.
    That menu and the left have the role of categories like your plugin, but when I installed it ceased to operate.
    I hope you could help me to fix that issue please.
    Thank you
    hope to hear from you shortly

    Comment by Dennis — June 18, 2009 @ 6:54 pm

  16. Very impressed by your wp-cumulus plugin. I really enjoy the plugin itself – there’s a lot of possibilities for something like this.

    Keep up the great work!

    I just used your flickr widged on my blog- http://hueroth.blogspot.com/

  19. Hi Roy

    Excellent and helpful blog! I got linked to you from a site that had your photo cumulus and I was so impressed – it looks GREAT!!!

    Guessing there is no equivalent for Blogger???

    Keep up the great work though!!

    Comment by Holli — September 21, 2009 @ 10:15 pm

    • Hi Holli. In fact, there is.

      Comment by Roy — September 22, 2009 @ 9:24 am

  20. Hi Roy,

    I liked your plugins for wp, is there a version of tagnetic poetry for ordinary sites as well? Would love to get my hands on that if you do.

    Comment by Joz — October 21, 2009 @ 12:01 pm

    • Hi Joz. There isn’t but the tutorials for using WP-Cumulus outside of WP apply to TP for the most part too. The flashvars are different, but you could find them in the php file.

      Comment by Roy — October 22, 2009 @ 12:59 pm

  21. How do I get to show ONLY on my blog page?

    Comment by REbecca — October 30, 2009 @ 9:39 pm

  22. Nice plugin you have there! I really like it. I would say it’s kind of ubiquitous these days: you can find all over the place, not only in WordPress. Keep up the good work!

    Comment by Oliver Mezquita — November 28, 2009 @ 4:57 pm

  23. Roy,

    I’ve installed WP-Cumulus under wordpress 2.8.6 and it works but the “bubble” is so left indented (not centerd on the width XXX pixels that i’ve setted. Could you help me please?

    Comment by Eduardo — January 13, 2010 @ 1:52 pm

    • Eduardo, did you change the settings under Settings->Wp-Cumulus, or inside the widget (Appearance->Widgets)? Depending on whether you’re using the widget or not, you need to change it in the right place.

      Comment by Roy — January 21, 2010 @ 9:49 am

  24. Thanks for the cloud tag.

    Comment by sundeep machado — January 21, 2010 @ 7:41 am

  25. dear roy,
    thank you for the cumulus plugin – we have ported it for a german open source cms without any problems.

    Comment by seb — January 25, 2010 @ 2:35 pm

  26. dear roy,

    i have a little problem with ur 3d cloud.
    i want to include it here (http://goodbois.de/blog/)
    soo the prob is this theme supports no widgets. and i cant change the size or color of the cloud 🙁
    or better: i tried to change it in the pluginsource, but it doesnt work.

    Comment by jessie — February 10, 2010 @ 3:28 pm

    • Jessie, dont’t change the plugin’s code. The settings are under Settings -> WP-Cumulus. The values in the plugin’s code are merely defaults that get set upon install.

      Comment by Roy — February 16, 2010 @ 12:14 pm

  27. Roy,
    I’d like to get in touch with you about your review of the iPazzPort and let you know about the new iNavigator that we are releasing next month. Please email me when you can and I’ll get you some details if you like.

    Comment by Scott — February 25, 2010 @ 6:54 am

  28. Hi Roy!
    In a theme about Photo widget I have left the comment with a code which should be inserted in hphbb2 a cursor that flash has earned, but at you it is visible codes are not passed, and it is very important and can be useful not only on my cursor, but also on simple sites and the code gives a transparency and the size for a cloud, has left in the comment the reference to the theme as all to make, can you will return a code? Then all will be happy on all cursors 🙂

    Comment by Kontrochka — March 20, 2010 @ 12:24 pm

    • Kontrocha, I’m sorry, but I can make heads nor tails of your comments…

      Comment by Roy — March 20, 2010 @ 8:32 pm

  29. Hello Roy,

    I love that cloud plugin and I am using it on my website.
    One quick question – since I am not the real programmer 🙂 – is it possible that when highlighting a tag in the cloud that no box around this tag appears? Just changing the colour?

    Thanks a lot for your help and providing such a cool tool 🙂

    Kind regards,

    Comment by Markus Leitner — April 17, 2010 @ 11:42 pm

    • Hi Markus. In the current version, removing the box requires you to modify and recompile the movie. In the next version I’ve removed the box completely because more people have asked me about this.

      Comment by Roy — April 18, 2010 @ 10:02 am

  30. Hello! I’m designing a blog, and I’m using your flicker widget (which is beautiful) and i wanted to know if it is possible to configure it to display over 20 photos (the picasa i use has 46 albums and still growing)

    Comment by erethakbe — May 16, 2010 @ 11:52 pm

    • Hi Erethakbe. The 20 images limit is there to keep the images from overlapping. If were to happen, they would pop in front of each other all the time which looks weird. The open source version, which does not use Flickr, comes with source code so you can experiment with it yourself.

      Comment by Roy — May 18, 2010 @ 12:01 pm

  31. Hi Roy
    Just discovered your blog, after finding your cool cloud tag at http://www.vancouverpolicemuseum.ca.
    I love the design, layout and content approach of your blog. It’s one of the nicest ones I’ve seen. Great job.

    Comment by Leslie-Ann — June 2, 2010 @ 5:10 am

  32. I loved your Cumulus so much, I blogged it!!


    Keep up the great work fella, you’re doing a fine job 🙂


    Comment by Richard Barry — June 7, 2010 @ 5:22 pm

  33. Hi Roy,
    I absolutely love this effect you’ve created. Great visual tool !
    I’m also a web designer, and currently engrossed in upgrading a website for an environmental summit in Aspen, Colorado. I know a bit about WP, but mostly work and design outside WP doing custom designs. I do love the word cloud and when I found your animated word cloud I knew it was exactly what the website needed for this environmental conference. This year we have Ted Turner, T.Boone Pickens and James Cameron (AVATAR) as our top speakers, and we are committed to ramping up the clean energy economy so we can save this planet ! I personally believe the situation is dire now, and we all have to do whatever we possibly can to turn this around, from the level of inner consciousness (staying positive) all the way to how much and what kind of resources we use.
    I am not saavy enough to take my static cloud and turn it into a movable one for the website, so I am writing to ask if you would consider helping me implement that. In return, we would be more than happy to list you as a sponsor on our webpage and in our program. I hope you will consider the idea.
    I look forward to chatting with you more, so feel free to contact me by email.
    All the best,

    Comment by Sue Winters — June 9, 2010 @ 10:37 pm

  34. Love your Cumulus and Photo clouds! Thanks so much for these tools. God bless. John

    Comment by John — July 17, 2010 @ 4:33 pm

  35. Hi Roy,

    Your plugin is very nice, but I have a problem with visualization.
    When I add “C++” or “C#” as a category in the sphere cloud there is only letter C without “plus” or “sharp”.
    What should I do to make their visualizability?



    Comment by Serge — July 30, 2010 @ 9:48 am

    • Serge, this will not be a problem in upcoming versions, but there’s only a limited character set available. That being said, I find it strange that basic punctuation characters are not displayed. I’ll look into this.

    Comment by Monica — September 15, 2010 @ 2:01 am

  37. I Roy, i come near you because i’m very interesting by your wpcumulus. Actualy, unfortunately i am lay off and i’m looking for a new job, i think that this module can help me.
    So, i’m working with a Mac, i have Adobe CS3, and Word, Pages, Quark Xpress..
    How can i use your program?
    Thank u for your help.

    Comment by Pascal — November 27, 2010 @ 11:27 am

  38. Hi Roy,

    Is WP-Cumulus available as a standalone Flash application to incorporate into HTML websites? Cool effect!


    Comment by bob bockstahler — January 10, 2011 @ 7:32 pm

  39. Roy,

    I think the tag cloud is terrific. As a matter of fact I plan to use it as a navigational tool on my homepage (which we are developing). Ultimately I would like to have Categories in bold and or larger font and some of my tags in smaller font.

    The tag cloud is a great way to quickly engage users and give them the ability to quickly find something of interest. Will let you know.


    Comment by Joe — January 31, 2011 @ 4:43 pm

  40. Nice work Roy, I am impressed specially from Tag Cloud..really you are GURU 🙂


    Comment by Ajay — April 16, 2011 @ 2:01 pm

  41. Hi Roy,

    I have your plugin installed and love it. Quick question… I’d like to change the code so it points to googles code in their ajax library here: http://ajax.googleapis.com/ajax/libs/swfobject/2.2/swfobject.js instead of here: plugins/wp-cumulus/swfobject.js

    Could you please tell where in the code I can do this?



    Comment by Mark — August 30, 2011 @ 12:01 am

    • SWFObject 2.x uses a different syntax, so you’d need to rewrite the function that outputs the html. Also, SWFObject comes bundled with WordPress now, and you should really use the enqueue_script function to load it.

    Comment by David — September 20, 2011 @ 1:08 pm

  44. Roy – I am trying to find a plugin for WP that displays a cloud of links to pages (or tags to pages with a page tagger plugin) but without the 3D/animated aspect of things and where the links are weighted based upon the number of times they have been clicked. Are you aware of anything like this?



    Comment by ihuntheads — November 2, 2011 @ 9:22 pm

    • I’m afraid I don’t know of a plugin that does that. The stock tag cloud probably can’t be limited to page tags only. A custom taxonomy might work, but that would require some coding.

      Comment by Roy — November 8, 2011 @ 10:34 am

  45. Hi,

    first of all let me say that wp cumulus is the best tag cloud widget out there, I’m a big fan of it 🙂

    I have a question regardin the instalation of the widget on my blog. I don’t want to install it using te plugin because I already have a facebook like box and a twitter widget installed by directly copying the code in my sidebar.php and if I add any widget using the “widgets” option in wordpress they get replaced and are not visible.

    Anyhow, I was wondering if there is a javascript or html code for wp cumulus that I could just c/p in my blog editor below other widgets?

    I tried adding it with as you instructed (copying this to the sidebar.php) but no luck.

    Thanks in advance for your answer, I apologize if the question is kinda dumb, I’m a wordoress newbie 😀


    Comment by Dejan — November 26, 2011 @ 4:38 pm

    • I don’t remember ever recommending to copy my code into a sidebar.php. In all likelihood, that won’t work. Are you sure I suggested that?

      From what you’re saying, I’m not sure why you would not want to use the plugin. In theory, you could rework the code so it can be used from your theme’s functions.php (or even a sidebar if needed), but I fail to see why that would be better. To me, a plugin seems the most logical way to add it to WordPress. For instance, If you incorporate it into a theme, it’ll disappear when you switch themes.

      Comment by Roy — November 28, 2011 @ 1:32 pm

      • Hi,

        the matter was that I installed plugins like facebook like box simply by copying the code, and I was only curious if that could be done with your plugin.

        As I said, I’m a newbie when it comes to these things, and I’m learning (sometimes very slowly :D).

        Anyway, I’ve added your plugin the “standard” way and it is great! 🙂

        Comment by Dejan — November 29, 2011 @ 3:31 pm

  46. Hello, Roy.
    Congratulations for your tag cloud. Beautiful indeed. As it is free software I guess it’s free for use, but I would like to ask you anyway if you do not mind to use the code of it for a Ecological Buildings Website (Solar energy and stuff).

    Thank you!

    Comment by Hector — December 23, 2011 @ 4:53 pm

    • WP-Cumulus is free both as in “beer” and as in “speech”. You’re absolutely welcome to use it.

      Comment by Roy — December 29, 2011 @ 11:27 am

  47. bonjour, Roy
    Déjà, je vous félicite de partager votre savoir. Ce n’ est pas doné à tous le monde.
    J ‘ aurais aimé savoir ou trouver le code source ou comment faire pour l’ avoir car je suis novice et je ne sais pas comment faire.
    Je vous remercie de votre réponse.
    Joyeux noel et meilleurs voeux.

  48. Hi!
    I just love your Flickr widget, but i can not manage to get it on my WordPress site.

    It looks like WordPress shortens the link in the dashboard and so it won’t work on the front of the page.
    Can you help me?

    Thanks in advance!

    • I’m sorry, but I don’t do that. You’re welcome to, but I wouldn’t know how to test the resulting movie, not knowing Croatian.

      Comment by Roy — January 9, 2012 @ 4:36 pm

      • I saw that you have croatican characters in your demo …

        I need this letters č,Č,ć,Ć,š,Š,ž,Ž,đ,Đ in tagcloud.swf ..
