    // Name: Image rotation using GD extensi
    //     on
    // Description:A function with the inten
    //     tion of rotating a Jpeg image 90° Clockw
    //     ise, Counterclockwise and 180°(Flip).
    // By: Karl Blessing
    //
    // Inputs:Source file ( path to the sour
    //     ce )
    Destination ( path to the destination, can be same as source if you want to overwrite )
    degrees (integer value of 90(counterclockwise), 270(clockwise) or 180)
    //
    // Returns:does not return a value, will
    //     save the destination, no indication if s
    //     uccessful is returned.
    //
    // Assumes:When writing this I found var
    //     ious behaviors between images with great
    //     er x than y's and so forth. Thus is why 
    //     all the condiotionals. The function has 
    //     not been tested for images with same x a
    //     nd y dimensions, and will not likely wor
    //     k. 
    IMPORTANT:
    You must have PHP 4.3.* or above for this function to work, a PHP version lower will not work. I was using PHP 4.3.2 for Win32, with GD Extension version 2 ( bundled with PHP ).
