preload or reload...
The main index page uses javascript to preload four of the eight animated thumbnails for this gallery index. I did this to help out you folks with slower modems while you read my pithy prose. However, preloading can sometimes leave animated GIF's hanging.
All the thumbnails on this gallery page should start moving as they load. If any are stagnant after the page is done, hit reload. The gallery will fill out fast.
...and keep your powder dry.
