That could be a problem. I think I explicitly create those directories in
the hook - I need to double check that.

For me it looked like the hashes weren't found. OK, more digging.

That's a good one. I'll try that.

Sorry, which directory is this? Since this is running on the server and
the files come from a bare git repo I create them on the fly... so how can
I make sure that the images get a hash?
