Blue boxes showing up around images that are links?

[AD Design]

Hi. In Mozilla and Netscape on a Mac there are blue boxes showing up around images that are links. I haven't tested on a PC yet. Does anyone know how to get rid of them? I think I've heard of this happening before, but can't seem to recall how to fix it.

Thanks!

Set border = 0

<img src="" border="0">

Or in CSS

img {border:0px;}
