I wrote this signature after a long drive when I was inspired by the thought of taking the referring information in a scipt and putting a "tricky" wrapper around it. Yes, the image above is really a PHP script that uses referrer information to make the image on-the-fly. I use a rewrite rule on my server to fool browsers into thinking its an image and allowing it in signatures. You may have picked up on that when you realized the image is actually a PNG file, but called a JPG file. It also throws in a random quote from some of my favorite movies - and if you happen to be on AOL or MSN, you get an extra treat.

It's a very cool signature... What's even more interesting is that he was banned from the Trillian forum for using it

Random quites are very good, and I've seen the extra treat when on a AOL hostname (AOL Sucks!)

Well i done an awful amount of resaerch on this and heres wat i came up wit.
"I think that this is probably running on a server with PHP. It probably has the GD library (http://www.php.net/manual/en/ref.image.php ). This allows you to create images in multiple formats on the fly. It can then just use the predefined variables $_SERVER["REMOTE_ADDR"] to find the ip and $_SERVER["REMOTE_HOST"]. Remote_host is a reverse dns lookup so it returns the host u r using. The script just removes the end of the string "optonline.net" for example and there you have it. To get the browser and OS, it uses $_SERVER["HTTP_USER_AGENT"], which returns a string something like this: "Mozilla/4.5 [en] (X11; U; Linux 2.2.9 i586)". YOu can then just parse the string and remove the relevant parts. The rest is just a random picked phrase. cool eh? its should be pretty easy in PHP, except i'm not sure how easy it is to use the GD lib!!"

Yeah he says he's using PHP and GD on his site. I'd just like to see how he's ouputting the text to the image.

There's a php function that writes text on an image for you. Can't remember what it is though, something like
[php]
ImageText(imagename, text, x, y)
[/php]

or something ...

(PHP 3, PHP 4 )
imagestring -- Draw a string horizontally
Description
int imagestring ( resource image, int font, int x, int y, string s, int col)

imagestring() draws the string s in the image identified by image at coordinates x, y (top left is 0, 0) in color col. If font is 1, 2, 3, 4 or 5, a built-in font is used.
[/php]

[php]
<?
// get ISP
$hostname = gethostbyaddr($REMOTE_ADDR);
$thesegments = explode(".", $hostname);
$reversed = array_reverse($thesegments);
$theisp = "$reversed[1].$reversed[0]";

Header("Content-type: image/jpeg");
Header("Expires: Mon, 1, 1999 05:00:00 GMT");

Header("Cache-Control: no-store, no-cache, must-revalidate");
Header("Cache-Control: post-check=0, pre-check=0", false);
Header("Pragma: no-cache");

//sig.jpg is a real image... This is what we write over

$im = imagecreatefromjpeg("sig.jpg");
$mycolor = imagecolorclosest($im, 255, 255, 255);

// some ip's dont have a reverse name... in that case just display their ip
if(is_numeric($reversed[0]))
{
imagestring($im, 3, 50, 22, "Your IP: $REMOTE_ADDR", $mycolor);
}
else
{
imagestring($im, 3, 50, 22, "Your ISP: $theisp", $mycolor);
}

Imagejpeg($im,'',90);
ImageDestroy($im);
?>
[/php]

You'll also need a .htaccess file that says:
RedirectMatch sig.jpg sig.php
