For my own studies and as part of a project for my PHP course, I have created an image hosting site. This site allows you to host your images for up to 4 weeks (28 days) and track views. It is designed to be lightweight and distraction free.

Additional purposes
This site also acts as an experiment to see how efficient the database is. Additionally, I want to know what performance I can expect of the server with my take on the configuration.
