1. make a graphic (you can do it in photoshop, paintshop, or even paint) that is 300 x 200 pixels or less (i think

2. upload it to the web. there are a lot of free services that will host it, such as photobucket, imageshack, piczo, and geocities. google one of those words in order to find them.

hope that helps
