Both of those programs have a cache directory where images are stored.
Perhaps there is some bizarre permission problem there.  For example, if
the apache user had rw but not x on the directory where the images were
supposed to be cached, it might get confused when it went to see if the
cache had already been written.  Or it might be something completely
different.  Maybe the cache directory is on a remote system with a clock
that is off.  Anyway, that's the place to look.

The directory is WorkDir: unless you have specified ImageDir:
