      * - does not support GIF functions in full
      *
      * Parameters:
      * - src - path to source image
      * - dest - path to thumb (where to save it)
      * - x - max width
      * - y - max height
      * - q - quality (applicable only to JPG, 1 to 100, 100 - best)
      * - t - thumb type. "-1" - same as source, 1 = GIF, 2 = JPG, 3 = PNG
      * - f - save to file (1) or output to browser (0).
      *
      * Sample usage: 
      * 1. save thumb on server: 
      * http://www.zubrag.com/thumb.php?src=test.jpg&dest=thumb.jpg&x=100&y=50
      * 2. output thumb to browser:
      * http://www.zubrag.com/thumb.php?src=test.jpg&x=50&y=50&f=0
