Creating an animated gif
Creating an animated gif is not too difficult. There are various programs available, some free and some not.
The most powerful tool is Adobe Imageready, and this tutorial will cover that.
Imageready lets you open quicktime movie files, and save them as animated images. Open your movie file, and resize it in the Image menubar. In the top right pallete, click Optimize, and then under the Options, change the "lossy" slider. The more lossy the image, the smaller the file (but worse the quality). Then, go to File and Save Optimized. It should save as an animated gif. Check to see that the saved file is under 3MB; if not, you'll hve to make it smaller and/or lossier.
