Changing position of "Detailed Images" box
 

Hello,
I'm sure this is a simple question, but I can't seem to find the right file.

When a customer clicks on the details for a product the detail page comes up....I want to switch the "Send to a friend" box and the "Detailed Images" box around. Which file do I modify?

customer/main/product.tpl. You'll see the includes near the bottom of the page...just move them where you want them.
