Product thumbnails on the BO Product Page suddenly not showing

[Obi]

Ok, another issue that I don't understand ...

Since completing the TB 1.3.0 install, most things have been pretty quick and painless (403 error on SEO & URLS page just got fixed with a simple setting change) but just prior to this I came across an issue in the products page of the back office. This part of the installation hasn't had an issue - at all - until today. As a matter of fact, a couple of days ago I created and uploaded a few more items to the catalog with photos without a hitch. Today (before change the mod_security yes/no switch in the back office) I decided to add another item to the catalog the same as I have done with the 183 previous products I have added - only today when uploading the images I get this...

I get this when I do a [view image info]...

And as this screenshot indicates - if I click the broken-link image - the image loads...

and as you can see by this filezilla screenshot - all of the images are indeed on the server where they belong...

I'm running the community default theme copied to a new name - which has been installed now for about a month with no known issues.
I've regenerated product images with no success - the broken-link-image is still present.

I suppose I'm at a point where I am not sure where/how to debug this issue except that it looks like TB is using the .htaccess file to locate images - but that hasn't changed either to the best of my knowledge. As a matter of fact, the site sat idle for a few days since my last product add session because I had other non-website tasks to deal with, and this is the issue I came back to when adding the next product.

Suggestions??

For some reason, this issue seems to have gone away on it's own. My language translations for the theme were somehow lost and after I restored them, the images now appear normally in the back office product page, even for newly uploaded images. I am really confused now because I see no reason why language files would have any connection to the display of images - but that is the ONLY thing that I changed as I was waiting for an answer here in the forum of what else to check - so I moved on to making a couple of css tweaks - which is how I discovered the theme was using the default language translations instead of the custom translations I applied weeks ago.
