There shouldn't be any unlabeled files around; the policy should ensure
that any files used or created by gallery are labeled properly. If
that's done, this rule shouldn't be needed.

Not sure about this one. What are the httpd_tmp_t files that gallery is
trying to read?

Setting the allow_httpd_anon_write boolean should remove the need for
these rules.
