They look exactly the same in IE8 and firefox on my computer - windows vista.
There is a gap between the footer graphics and the section above that doesn’t look like its meant to be there, in both browsers. Apart from that the images all seem to be lined up properly.
looking closer -
the bottom images are in a paragraph, inside a table cell, inside a single row table.
The gap above seems to be coming from the top padding of the paragraph tag. Try removing the paragraph tag, you shouldnt need it.
