I use the following function, but I wrote it almost a year ago now so it may not be the best way of doing it. You've got to remember though that manipulating images is an intensive task in itself.

PHP Code:


			
function doResize($szSource, $szDestination, $szExtension, $iResizeWidth, $iResizeHeight)
{
    declare(ticks = 1)
    {
        $szExtension = strtolower($szExtension);
        
         switch($szExtension)
         {
             case('jpg'):     $pSource = imagecreatefromjpeg($szSource); break;
             case('jpeg'):     $pSource = imagecreatefromjpeg($szSource); break;
             case('gif'):     $pSource = imagecreatefromgif($szSource); break;
             case('wbmp'):     $pSource = imagecreatefromwbmp($szSource); break;
             case('png'):     $pSource = imagecreatefrompng($szSource); break;
         }
         
         $pResized = imagecreatetruecolor($iResizeWidth, $iResizeHeight);
         list($iWidth, $iHeight) = getimagesize($szSource);
        
         if(!imagecopyresampled($pResized, $pSource, 0, 0, 0, 0, $iResizeWidth, $iResizeHeight, $iWidth, $iHeight))
         {
             return false;    
         }

        switch($szExtension)
        {
             case('jpg'):     $pResult = imagejpeg($pResized, $szDestination, 100); break;
             case('jpeg'):     $pResult = imagejpeg($pResized, $szDestination, 100); break;
             case('gif'):     $pResult = imagegif($pResized, $szDestination); break;
             case('wbmp'):     $pResult = imagewbmp($pResized, $szDestination); break;
             case('png'):     $pResult = imagepng($pResized, $szDestination); break;
         }
         
        if($pResult)
        {
            return true;
        }
            
        return false;
    }
}
