Not being so well-versed in indexing (just starting using those in MySQL 5), I don't understand how having a unique index on the photo_filename column will prevent an insert of a duplicate value.
Is that function a part of creating a unique index? Does it cause MySQL 5 to screen inserts for duplicates and reject them? ???
