tidypics won't generate thumbnails?

For some reason I cannot get tidypics to display thumbnails. Instead, when I view albums, it uses a "No images" blank thumbnail, and each picture is a grey circle with a question mark ( ? ) in it. If I click on that, I clearly see the image, so I know it's being saved to the server.

Any help?



I also thought that it might help to say that I have Imagemagick running properly on my server too...Don't really know where else to go from here.
