<?php

} else {
    if($Image->checkURL($_POST['url'])) {
        $Image->setImage($_POST['url']);
        $width = $Image->getXY('x');
        $height = $Image->getXY('y');
        echo "<table border=\"0\" cellpadding=\"0\" cellspacing=\"0\">";
        for(;$y<$height;$y++) {
            echo "<tr height=\"1\">";
            for($x=0;$x<$width;$x++) {
                echo $Image->getPixel($x,$y);
            }
            echo "</tr>";
        }
        echo "</table>";
    } else {
        die("Please Enter a Valid URL.");
    }
}
?>

it uses cURL to check if the link is valid. then it checks for the file extension to use the correct image grabber thingy. i also added a feature to change the output string.

EDIT:
updated the getPixel function. the old one outputted shitty span tags so now it looks way better.

COPY !! 1> :( lol

Nah, anyway I have a few suggestions...

1. Make the text white
2. Use the TD tags instad of span tags for the colour css (save markup)
3. Suppress errors (with @function() or die();) (I tried a broken image earlier and got thousands of php erros lol)
4. Get rid of id="at" ?

about the thousands of errors, just add a check for that and it will get rid of it.

i also put this together in like 2 hours. so there are many errors to come from it.

EDIT:
updated script with all your suggestions

up-dated the code to look exactly like the picture, except for the transparent pixels.
