That's awesome. I tried the following and I got a long list of numbers
8 digits long.
$myFileAsString =
file_get_contents("http://www.mycompany.com/product_images/composite_standard_sm/318_1_SM_100.jpg");
$image = imagecreatefromstring($myFileAsString);
$width = imagesx($image);
$height = imagesy($image);
echo "<p>the height is $height and the width is $width </p>";
for ($i=0; $i < $width; $i++) {
for ($r=0; $r < $height; $r++) {
$rgb = imagecolorat($image, $i, $r);
echo $rgb;
echo "<br>";
}
}
which gave me something like this:
16645629
16711422
16777215
16711422
16711422
16645629
16711422
16645629
16185078
15790320
15329771
15066599
14803427
14737634
14737634
14737634
14606048
14737634
15132392
15658736
16053494
16316666
16645629
16711422
but a lot more of that.
