Change number of items per page, and adding multiple images per product

As I thought, you have a Template Monster template. I suggest searching on them to see issues others have had with their templates. It may be difficult to modify their standard layout, as they do things in their own unique way and the usual advice given here may not apply to their templates.

Cool now I am dying to know, how did you identify it as a TM?

First, I have seen that 4-product limit on the listing before on one of their templates.
And once I could see your site, a View Source showed the template name /themexxx/ which is a standard kind of name for them, and the code is uniquely their style... convoluted and replacing the standard meaningful Zen Cart tags with their own cryptic ones.
