You should ask for help in the help forum, but you use the tags like this, [img]here is the picture URL[/img] remember to have the slash in the last tag.

Edit: Apparently you just figured that portion out for yourself, but you're using Geocities, which won't allow you to use pictures, you should try a better host.

Edit2: I uploaded the picture myself, just to make things more easy on your part. I've also changed the extension to .gif so that it loads quicker.
