Ok, next question... what is it that is wrong? I can't see any problem with the bottoms of pages being cut off.
I presume you are still working on your header/logo area.
You could use the spacing fix between product listing lines, as your images touch top to bottom.
PHP Code:
/* space & border between listing items */
.productListing-odd td, .productListing-even td {
vertical-align: top;
padding: 0.5em;
margin-bottom: 1em;
border-bottom: 3px double #aaccbb;
}
The padding also controls clearance between elements of each product, and you can set that separately by adding another value:
padding: 0.5em 1em;
The first value is top & bottom, the second is left & right.
