I have rapidly upgraded the AtomIC Album to accept and display GIF images. Please note that due to licensing costs, we can do NO manipulation of the image if it is a GIF, so even if you specify the thumbnail option in your Album code, the image will remain full sized. If you wish to be able to display thumbnail links for your pictures, we have to recommend you edit them using PaintShop Pro or similar and save them as JPG...
The same problem will apply to anyone looking through your album if they elect to show the thumbnails - they will get thumbnails for JPG's and fullsize for GIF, which may look a little ugly.
Its possible I'll put a dirty hack in place to get round this by making the browser do the resize, but its a dirty hack and I might not ;)
Steve.
