Extra space in div in IE and firefox

In both Firefox and IE I am getting extra space at the bottom of one of my divs and I can't see where it's coming from. I made the background color of the div red so you can see which div has the extra space.
In addition, in IE there is a 1px of extra space on the left edge of the div.

Put one of the following code in your css file

Code:
a img
{
display:block;
}

...or...

Code:
a img
{
vertical-align:top;
}
