i thought there were directions on the MCCI website IMG code should work, not 100% just tryin to help
Click the Insert Image button , and paste http://www.maverickcometclub.org/logo.gif into the box that appears. Works for me. You also need to delete the excess formatting codes you have there, the "[/img] [/url]". I would suggest bringing your list of cars down to the next line, and putting the MCCI image next to the picture of your car to keep the height of your signature to a minimum.
