The trick to uploading them on flickr is that only the original sized version will have the animation. I create versions that are around 500 pixels wide and upload them as private. Then I take the html code from the original sized version (all sizes link) and place the animation in a comment of a public photo.
Here are some of the ones I've posted in the past.
