I find I often have to handle photos in CMSs, so I wrote this class. It doubtless needs improvements, but it works pretty well.
<?php
class picture

        var $save_dir;                     //where file will be saved
        var $filename="spacer.gif";        //default file name initially 
        var $error_message="";             //string to be output if neccesary
