Linked Images in Firefox Showing Underline

My site’s links have the text-decoration property set to “underline”. In Firefox, the linked images are showing an underline, but in IE and other browsers, that underline doesn’t show up.

I’ve seen some other articles and posts (like [url]http://archivist.incutio.com/viewlist/css-discuss/56774)[/url], and the only solution I’ve found that works is “display:block;”. I cannot use that property in my site, as it moves the images from where they are supposed to be. Does anyone know of another way to make this work?

P.S. This is what I currently have my “img” CSS property set to:
img {
border:none;
text-decoration:none;
line-height:0;
}
