Agreed.

I hate hashes when they aren't used to reduce the storage requirement
for something or are needed for cryptographic security (such as
passwords).  Hashing the contents of a file to quickly determine
whether two files are identical is one thing.  In this case, it makes
it hard to trace the origin without improving security (non-issue in
this case) or saving space.

There's no perfect solution to the fact that slashes can't be filename
components, but I don't think this really has to be absolutely
perfect.

Or moved to XDG_CACHE_DIR/kphotoalbum/<db>/CategoryImages?
