Using ZP 1.4.1.3

I can't seem to crop any Image thumbnails. When I pull up an image, click on the thumbnail to edit the cropping, I see the thumbnail displayed at left, the large box where I am supposed to view the full image so I can crop, contains the little broken image link icon instead of the full image, and of course, the thumbnail preview box is blank.

Is this a configuration error of some kind?

Sorry, please upgrade to the current release, your version is seriously outdated. We can only support the current release.

Will do, thank you.
