widget image not displaying in IE

Text widget displays properly in Opera, Safari, and Firefox. But doesn’t show up on Internet Explorer.

I have added the following code to a text widget (its basically 3 separate buttons that stack on top of each other and each one links to another page)

I read on here about putting the absolute exact dimensions of the graphics in the code, but didn’t know where to put it or if that was even correct.
