BTW, for those curious some instructions for making GIF's are here:

First collect the series of .jpg frames (they can be captured as ANY image format, but most programs default to making .jpg frame grabs). The max number of frames that will fit in a 100x100 GIF sized at 50K (this sites limit) is probably 8 or less.
Open the first frame with the gimp, and then use LAYER->NEW to create a new layer to paste the next frame on top of. Click OK in the pop up window to do it.
Open the next frame with the gimp and goto the new window with the frame. Use Select->all and Edit->Copy to get the image into the clipboard. Now paste it onto the first window (base frame) with Edit->Paste. Finally use Layer->Anchor_Layer to finish the paste. Open the third frame in a new window and repeat the operation to create the next layer on the original image opened. Once all of the images have been pasted you can close the second to last images you opened.
Now use Tools->Transform_Tools->Crop to cut out a square portion of the image you wish to convert into the Avatar (well the avatar doesn't HAVE to be square, but it will be limited to 100x100. No side may exceed 100 pixels in the end.) Right now we don't care about the size, only the shape. Click the mouse pointer over one corner of the square, drag it to the far corner, and look at the dimensions to see you have a square. After letting go of the mouse button you'll have an outlined area that will be cut. Finish with the enter key.
Now go to Image->Scale_image. Make sure the link is locked so both dimensions scale together. Reduce to 100x100 pixels and click Scale button.
Now use Image->Fit Canvas_to_Layers to remove the unwanted part of the image.
You now have a stacked image with all of your frames. Save it as a GIF using File->Export_As. Give a file name, select image type as GIF from the drop down box and hit export button. In the popup, click on the animation box, and click export. You might want to experiment with different animation speeds, 100 to 200ms usually works.
Finally, cross your fingers and hope your new GIF is under 50k in size. If not, you might have to stack fewer frames, or use a smaller size than 100x100. The Avatar I just did here came in at 48-49K (Phew!). YMMV!
