David, check out your image cache settings at /admin/settings/imagecache. There are presets in there that specify sizes. You can change any of the default sizes defined by Ubercart to adjust the images.

Sorry for the dumb question.

Extremely appreciative for the quick response.

I found this thread by searching for how to change product sizes. I see I can change the thumbnail sizes here, but how do I change the size of the full size image that appears when you click on the thumbnail? That is too small for my needs and I don't see that setting anywhere. Thanks!

That should be the actual size of the image. Upload bigger pictures, and the thickbox images will be bigger.

Thanks. I guess the image shown in the thickbox is the actual size I uploaded, but it is being dynamically resized within the page, which makes it look crappy. I'd rather have the user scroll and see a good image, than not scroll, and have a crappy image fit within the window. Any way to fix? URL in question is http://justforcnas.com/node/1
(Click on second image to see how bad it looks)

I found the thickbox admin screen, but it doesn't let me specify anything about size of image displayed...?

Thickbox options
Enable for image nodes
Automatically activate Thickbox for all image nodes (requires the image module).
Enable for login links
Automatically activate Thickbox for links to user/login.
Deactivate Thickbox on specific pages:

What I did is create a preset called "Enlarged" or something, and then in my product template (either using Contemplate or just node-product.tpl.php) and set the link for thickbox to something such as..

<a class="thickbox" href="/files/imagecache/enlarged/files/FILEPATH.jpg"><full screen img></a>

Of course change your "enlarged" path to whatever you call your preset. You'll also need to pull the filepath from the $node object (if you're not already). I think it's $node->field_image_cache[0]['filepath'].
