Trying to put info from files into database

You cannot use the upload library for files that are already on the server.
You need to use the the directory helper to load the folder's file into an array.
The file helper will give you some the information you want but I don't think you can get the image size, so you would need to use raw PHP or there maybe a library available but that I don't know.

A good decision is based on knowledge and not on numbers. - Plato
