Image Import triggers "Access Denied"

"Access Denied" error while attempting to import images can be fixed by increasing the
max_allowed_packet = 1M setting in /etc/my.cnf.

The default mysql my.cnf setting is max_allowed_packet = 1M. If you are attempting to import from a directory with more than 41 images, regardless of size, or the actual number of images being imported, the "Access Denied" error may be triggered.
