Looks identical to me in Netscape 4 and current mozilla. Reporter, please provide: 1) Your build id 2) A clear description of the problem (a screenshot, maybe?)

this is probably the same as was just reported in bug 109242 - allthough a little unclear. There are white stripes between the orange gifs on right side. Looks like bug 22274. Doctype is <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html40/loose.dtd">
