Image Fade-In, Transparency Help Options

[rockinxxl]

Hi, I'm using:

table table table td
{
filter:alpha(opacity=80);
-moz-opacity:0.8;
opacity:0.8;
}

to make my tables transparent. unfortunately, this also makes the images transparent. Is there anyway to either have the image fade-in (100% opacity) on a mouse-over or to just always be at 100% opacity regardless of the transparency set in the table?

Thanks for your help.
