I have downloaded a .css file from a free site that says it is OK to modify code to suit individual needs. I will post the code and see if anyone can help.

I cannot get more than 12 images to show in each catagory. Image set#1, #2, etc.

This is the part just below the <body> where I have images 1.gif 1a.gif etc.

If I put more than 12 images or <li> in they become squished at the bottom.
