To align the images in the centre, replace the css with:

.postbitlegacy .postfoot .textcontrols a.abipinfo, .postbit .postfoot .textcontrols a.abipinfo  {
	background: url({vb:stylevar imgdir_button}/info.png) no-repeat transparent center;
}
.postbitlegacy .postfoot .textcontrols a.abipinfo:hover, .postbit .postfoot .textcontrols a.abipinfo:hover  {
	background: url({vb:stylevar imgdir_button}/info.png) no-repeat transparent center;
}

Change the second image path to be the image you want displayed when you hover over it.

If the image disappears make sure you've put the .hover set of css entries. basically it states not to change when you hover over it. If it's missed out, the image disappears.
