Nice tent, must be hard to put up. There's a bug ATM (There's ticket open somewhere for it) that crashes the system when reading very large folders, I'm wondering if you've run into this and not just a jpeg problem. Can you place one of the 'suspect' images locally and see if it loads? This would have the effect of determining if the file compression is at fault, networking suspect, or are we dealing with the known bug.

A tool like 'Mediainfo' would give a better comparison to different images an perhaps leave a clue. The only suggestion at this point would be some sort of batch process of conversion, and wouldn't be my or your first choice.
