Adding content to the products selection page

Hello all. In the past (v6), I was able to add some information to the product selection page. I cannot remember how I did it. I migrated to version 7 and need to change some of the info I place on the products page. I have looked hi and low and cannot find were I did this. From v6 to v7 the default image size is different. Can that be reduced?

I found the location in the system for adding content to the products pages. It is located in item groups. Each item group can have its own page content and route to each group. I hope this may help others that would like to do the same.

@Ryan does it work alright?

Old post I know. Everything works fine.

I would like to reduce the image size and increase the images per page to 8. Is this a server side change or theme change?
