php Convert image to ascii Output image

This PHP function creates a simple ASCII artistic rendering of a JPG image. It uses Guangdong to do the heavy lifting, and some simple shifting to assign colors. The color is then transferred to a hexadecimal value and the resulting text is output to the browser. ASCII from Image Arts with PHP is now easy.

function image2ascii( $image )
{
// return value
$ret = '';

// open the image
$img = ImageCreateFromJpeg($image);

// get width and height
$width = imagesx($img);
$height = imagesy( $img);

// loop for height
for($h=0;$h<$height;$h++)
{
// loop for height
for ($w=0;$w<=$width;$w++)
