I made some progress but I still need help. I figured out how to remove the folder tab image on the top border, leaving a thin line around all 4 sides. That was my second choice if I couldn't remove the border completely.

But that still doesn't look the way I want. Mainly I'm trying to get the detailed image to appear higher on the screen by removing the folder tab image and border. Now I've removed the folder tab image but the detailed image doesn't display any higher. So back to my original question. How do I remove the border completely? And I need to do this in a way that the top of the detail image displays where the border used to be (actually, where the folder tab image used be, ie, top of this section of the page). Remember, I've modified the cart so the detail image displays where the thumbnail used to by default on the product pages.

Any help will be appreciated.

In case it is helpful to other newbies like me trying to understand how some of the x-cart templates interact, here's what I did to remove the folder tab image around my detailed images on the product page:
1) copied the dialog.tpl into a new template I called dialog_detail_image.tpl, then removed the reference to background="{$ImagesDir}/dialog_bg_n.gif" in the new template.
2) changed the reference in modules/Detail_Product_Images/product_images.tpl to the new template created in step 1, ie, from dialog.tpl to dialog_detail_image.tpl.
