Go to the filters tab and find animation. Then, click on spinning globe. The larger amount of frames, the slower the head rotates. I would suggest having more frames than having a small amount so we could see all the details. I would usually put 60 frames. Be patient and wait for the sphere to load. If you want to see the globe spin, filters - animation - playback. When it's finished loading, save it to whatever, BUT you have to save it as a .gif image. So, the default type of image would be .xfc or whatever, so change that part to .gif. A window will pop, so click "save as animation." tada you're done :P Just upload it to imageshack.us or whatever and click the full size image. Then, click and drag to a post :]
