Using the IE browser, please have a look at my page located at http://www.thereefman.com/cleaners.html
There are a couple issues with the spacing as you can plainly see..
1) The gaps between each of the images which are linked to my shopping cart
2) The gap at the bottom (which is visible when looking at the link in its parent frame at http://www.thereefman.com)
Any help is greatly appreciated!
