问题 I have a table that has a photo column in it, one of the users decided to start saving 20MB images into the field, which consequently caused the database to jump up in size by a factor of 6 in less than a year. So my ultimate goal is to iterate through the table, pull the image, resize and crop it, then save it back to the database.
