In order for this to work you will need wkhtmltopdf and the imagemagick tool convert.

On ubuntu you will just do:

sudo aptitude install imagemagick wkhtmltopdf
<?php

// save this snippet as url_to_png.php
// usage: php url_to_png.php http://example.com
if (!isset($argv[1])){
    die("specify site: e.g. http://example.com\n");
}

$md5 = md5($argv[1]);
$command = "wkhtmltopdf $argv[1] $md5.pdf";
exec($command, $output, $ret);
if ($ret) {
    echo "error fetching screen dump\n";
    die;
}

$command = "convert $md5.pdf -append $md5.png";
exec($command, $output, $ret);
if ($ret){
    echo "Error converting\n";
    die;
}

echo "Conversion completed: $argv[1] converted to $md5.png\n";
