Any idea? Please!

What happens when you use a PNG file?

Hi, I got an empty picture 0x0 pic small 33 byte :-)And I found the error in the bottom part

header('Content-type: '.$mime);switch ( $type ) {	case IMAGETYPE_JPEG:	ImageJpeg($dst, null, $Q);	break;	case IMAGETYPE_GIF:		ImageGif($dst);				break;	case IMAGETYPE_PNG:		imagepng($dst);				break;	default:  trigger_error('Failed resize image!', E_USER_WARNING);  break;	}

And now it works!
