Its correct, you should not store the images data into the database but
a reference to the images location on the server. So you are right with
your suggestion to store the image outside the database.
But the OP is right to load the image via imagecreatefromstring or
imagecreatefromjpeg, whatever, if he wants to merge two pictures together.
