Recently, Picasa started serving its RSS feeds over https. From what I can tell, this has caused quite a view “clients” to fail. Digital photo frames seem to be affected, and so is my Flickr widget. Fortunately, there’s a quick fix.
I’ve run a few tests, and it seems that simply removing the “s” from “https” fixes the issue. Every feed I tried could be called up over regular old http as well, and all of them worked with my widget.
