I have the same problem. The problem seems to be with the Flickr gallery. The flash loads on my local computer, however as soon as you upload it to the website, it does not work. The galleries worked fine till a couple of days ago. I redownloaded 220, uploaded the sample web directory and it still does the same thing. When you use Flickr, it seems that Simplegallery just doesn't get the images anymore. I even uploaded a gallery to different webhosting providers to see if it was something just on the original hosting server or on different unrelated servers. It was the same on all of them. Again, there was no changes made to the working gallery that was working earlier last week but quit working in the last two days.
