Hello - one of my programmers has created some pages where images are store in DB, but I would have it so when a category, sub , sub sub, is created, I then see new folders on my server, where the images are placed. Is it a big thing to change that from DB to files storage.
It depends on the way your scripts are organized. If the development was fully object oriented, there is a good chance that only a few image references in one module have to be updated. But if the retrieval of images is hardcoded throughout the program to increase script execution speed, it can be a time consuming job to change all image storage and retrieval actions and test them for the new situation.
