Random seems pretty random. Your image test is flawed.
Try this to see some noise:
<?php
header("Content-type: image/png");
$img = imagecreatetruecolor(500,500);
$ink = imagecolorallocate($img, 0xAA, 0xAA, 0xAA);
imagefill($img, 0, 0, imagecolorallocate($img, 0x8F, 0x0D, 0x57));
for($i=0;$i<500;$i++) {
for($j=0;$j<500;$j++) {
imagesetpixel($img, rand(1,500), rand(1,500), $ink1);
}
}
imagepng($img);
imagedestroy($img);
