Photos versus Image Upload?

Regarding Supreme Directory Theme and Details page.

I have a custom image upload field…a single image. It is loaded into its own Details tab.
I also have the typical images in the Photo Tab.

I have turned off the Geo>Design>Details>GD Modal option.

I note that for images in the PHOTO tab, this causes a single click to open the image in another page. Therefore, the image could be printed.

However, for my custom field image, it just stays inert…it does NOT open that image in another page, which is the whole reason I’m willing to turn off the GD Modal option! Really, I only want the user to be able to click and print THAT image. I don’t care about the photos! (Really would prefer those still in lightbox, but will accept that it’s a one option for all!)

I tried to use CSS to turn off the modal ONLY for the custom field, but that, of course, didn’t “make” the custom field open in new window.

Can you tell me what “magic” you have applied to the images in the photo tab? Can I borrow some for the custom image field, too?

Let me know your thoughts!
