Hello Everyone; I want to create an imaging application for doctors. They can review, manipulate images and of course print. Our main goal is to create a web application (Based on PHP) that can operate the below: - User management (Register a new user, login page, ...) - Gallery creation (to review the images (with the info)) - A minor manipulation studio - Report Printout of images. The user should be able to upload an existing image and be able to customize it and save it to his desktop.
