An existing website (search engine) needs additional features which require Ajax, PHP/MySQL.
1. Overlay ajax form that validates inputs and allows users to upload simple information (some text fields, and 1 image upload) that will subsequently be public on the homepage of the site. The image upload will have to be image-merged with a default background image through PHP and then uploaded and entered into a database.
2. Some admin back-end that allows to disapprove or approve any form submissions before they are made public on the homepage.
