Quick & Simple Question

okay, one time I was browsing a forum, not linuxquestions.org, and I saw this one guy who had a unique signature. His signature said "Your IP is xx.xx.xxx.xxx" only the x's were my real IP. I went to view source, but i saw that it was actually an image! How is this possible? Could someone tell me how to manage such a thing?!?

The image was probably being pulled from his server, with a bit of quick php scripting and using gd for graphics you can quickly create an image and overlay some text. The IP itself can obviously be found from examining the REMOTE_ADDR environment variable.

yeah I figured the remote server part, but could someone help me with the code? I'm quite interested in writing my own

I have PHP installed, and am quite proficient at it. If someone could just outline the basic process to me, I would be able to carry on myself

Thanks!

Basically:
1) Manage to print the IP of someone who views your script.
2) Manage to put some text into an image using gd.
3) Manage to put the IP into the image.

Which bit's holding you up?

Printing the IP into the image is the part that's lagging me up the most. I think I've got it now, though

Code:

<?php
$img_number = imagecreate(275,25);
$backcolor = imagecolorallocate($img_number,000,000,000);
$textcolor = imagecolorallocate($img_number,255,255,255);

imagefill($img_number,0,0,$backcolor);
$number = " Your IP is $_SERVER[REMOTE_ADDR]";

Imagestring($img_number,10,5,5,$number,$textcolor);

header("Content-type: image/jpeg");
imagejpeg($img_number);
?>

It's working for me, but please test it for me, everyone, especially those behind a firewall and such. The link is:

Thanks everyone!
