Spaces in IE and FF betwen images

in firefox buttons are displayed like i want it to be ( no spaces betwen them) but on IE buttons are seperated.

How to avoid that ?

code of div containing menu:

<div style="position: absolute; top: -737px; left: 16px; height: 104px; width: 640px; margin-left: 0px;"
