Marketpress Multisite User Shop Product Photos

Marketpress Multisite User Shop Product Photos.

Right now Users are only able to upload one main photo. Other photos are generated within the about product section and added under there, which I do not like.

I would like to have additional photo widget where it automatically sizes the photo and only allows users to add 5 photos per item.

What is the best solution? Is the main photo widget/section able to be modified? Or can I duplicate that section and direct it as additional images in code?
