Hmm - I was always given to understand that execute permissions on a
directory meant that the directory could be listed / searched, rather
than merely seeing whether a given file was present within it
(conveyed by the R bit) (qv.
http://www.dartmouth.edu/~rc/help/faq/permissions.html)

Nonetheless, write permission on a directory means the ability to
delete files within that directory, which might be the easiest way to
get there from here (you won't be able to write individual files per
se, but you will be able to open -> change -> delete original ->
save).

Another way of hacking it might be to stick a "chmod g+w
<photodirectory>/*" in the appropriate crontab.

For doing exactly what Dave requires, it looks as though ACLs might be needed:

Hope this is of some use,
