Issues

I realise that i have not put to good use php in several areas that i can think of, this is due to time and inexperiance in php. Validation in several areas are missing..crop tool not part of the userbility aspect...image fime validation is another, im sure there are a few more but my knowledge in php is not to a high standard but i aim to carry on and persue php as it is a vital tool to have experiance in using for web design.
