I'd like to help out (two 16 core machines) but I don't know any java. A lot of these images run through f5 seem to hang at a German error message from HuffmanDecode.java. Also f5 doesn't seem to take "jpeg" but needs "jpg"

Does this header need to be repaired or is that part of the processing in some other way?

How do I setup the workflow for password brute forcing?
