The "Fivefold Presents" image is only the first frame. They are fairly big GIF files, so will take a little while to download if you're on a slow connection. (I've edited the links message above to give the sizes). Having said that, I do sometimes have problems with animated GIFs in my web browser, a refresh / reload or quitting and reopening can often fix it, or save the images to your hard drive (once they've full loaded) and open them in anything that can display animated GIFs.
