Illustrator CS2 Question: Please Help

[sitesbye]

I am making a 102x33 button for my web site with Illustrator CS2. The background color is an image because I could not figure out how to do the fill background like you can with Photoshop(I am new with Illustrator). When I go to save the file it puts a white border around the image. Is there a way to get rid of the white border? You can view it here
