Question:
Can I link my thumbnail images in the shopping cart to larger images?

Answer:
Yes the cart can automatically link your thumbnail images to larger images or HTML pages even. This works with both HTML forms and databases.

Notice the new "img2" tag.
Put the purse in the cart.
Click on the thumbnail.

Noticed some of the thumbnails there are linked to larger ones.
This is how images are fed to the cart.pl script with databases:
||||||purse.jpg::purse_large.jpg|||
instead of only:
||||||purse.jpg|||

See details in various sections of Template.html and near the end of section 13 of the ReadMe.
