Internet Thumbnail Problem - Comodo Firewall Help?

[hech54]

I'm having problems with thumbnails NEVER loading here:
http://www.mymemory.co.uk/

Firefox, IE, or Firefox w/ IE Tab....all I ever see is:
Waiting for images.mymemory.co.uk.... in the bottom left corner of the window.

So far I've:
Turned off my firewall.
Turned off NoScript
Cleared out cookies and others with CCleaner
...and everything else MyMemory has suggested.
NOTHING works. I do not get thumbnails of their products.
It used to work if I signed in or onto my account....sometimes...and
now even that is no help at all.

Any other suggestions? So far the folks at MyMemory have been everything
from stumped to downright dismissive.

I think I just figured this out but don't know how to fix it. If I change my Comodo firewall to Training Mode....all of the thumbnail load. Is there a way to "allow" Comodo to load the images from the above site?
