What do you mean with "in hex"? Hex is a number system. It only exists to
make handling binary data easier for humans.

Aha. So you just want to "send the image".

Well, you *need* the header ("Content-type: image/gif"); to tell the
browser that you're sending a gif. It can not determine that by itself.
If you don't send the header the browser will try to interpret you gif
image as HTML code, which usually gives, well, fascinating results :)

Try
echo pack ('c*', $img);
Or if that doesn't work:
foreach ($img as $val) {
echo pack ('c', $val);
}
