Are you using GIMP? If so, go into Filters >> Animation >> Spinning Globe. Select that, and set the frames to about 18 or 20. Save as animated GIF and upload it to Imageshack.us. Use the forum code to post it here.
Accually, for a better quality and slower head spin thats easy to examine go to Filters - Animation - Spinning Globe and set the RGB to 0 and 50 frames. Much better.
