The HTML image renderer didn't work for me for some reason, but here's a version that
does...
echo '<table border="0" cellspacing="0"
cellpadding="0">';
$im = ImageCreateFromJPEG("IMAGE NAME");
$width = imagesx($im);
$height = imagesy($im);
for ($cy=0;$cy<$height;$cy++) {
echo '<tr>';
for ($cx=0;$cx<$width;$cx++) {
$rgb = ImageColorAt($im, $cx, $cy);
$col = imagecolorsforindex($im, $rgb);
printf('<td width="2" height="2"
bgcolor=#%02x%02x%02x></td>', $col["red"], $col["green"],
$col["blue"]);
}
echo '</tr>';
}
echo '</table>';
