This document describes a CodeIgniter application that allows uploading and displaying images stored in a MySQL database. The .htaccess file configures URL rewriting. The database configuration connects to a local MySQL database named "images". The MainController handles displaying images, uploading new images, and saving images to the database using a model. The MainModel interacts with the database, saving image titles and paths and retrieving image data. Views display the upload form and retrieved images. Configuration files setup default routing and autoload classes.
