Where are you getting it from?
What format is the image in?

You probably want a sequence of:

http://uk.php.net/file_get_contents - get the image from a file or URL

http://uk.php.net/imagecreatefromstring - create a GD image object

http://uk.php.net/manual/en/function.imagesx.php
http://uk.php.net/manual/en/function.imagesy.php
http://uk.php.net/manual/en/function.imagecolorat.php

- loop over all the pixels in the image, converting to whatever your
representation is (looks like hex representation of brightness level in a
greyscale image?)
