Hi,
See http://devel.webwork.rochester.edu/twiki/bin/view/Webwork/InstallationManualV2pt4#Image_depths_database
for instructions on adding the depths table to your database. You might also review the other instructions for updating the database as well since there have been several database changes since webwork 2.2 (the depths table was introduced in webwork 2.3).
Run bin/wwdb_check (if needed) and bin/wwdb_upgrade to bring the databases up to date -- but read the directions in the upgrade manual first. :-)
