I just wrote a script quickly (under 30 minutes) to generate a unique image from your IP Address. Later I hope to make a decoder and clean up the code.

PHP Code:
<?php

    //tell the browser we are a png image
    header("Content-type: image/png");
    
    //Get Information
    $usrIP = $_SERVER['REMOTE_ADDR'];
    //$usrIP = "123.456.789.123";
    
    //Colours
    $colourR[0] = 54; $colourG[0] = 100; $colourB[0] = 139;
    $colourR[1] = 79; $colourG[1] = 148; $colourB[1] = 205;
    $colourR[2] = 92; $colourG[2] = 172; $colourB[2] = 238;
    $colourR[3] = 99; $colourG[3] = 184; $colourB[3] = 255;
    $colourR[4] = 70; $colourG[4] = 130; $colourB[4] = 180;
    $colourR[5] = 240; $colourG[5] = 248; $colourB[5] = 255;
    $colourR[6] = 16; $colourG[6] = 78; $colourB[6] = 139;
    $colourR[7] = 24; $colourG[7] = 116; $colourB[7] = 205;
    $colourR[8] = 28; $colourG[8] = 134; $colourB[8] = 238;
    $colourR[9] = 30; $colourG[9] = 144; $colourB[9] = 255;
    
    
    //create GD Image or exit on error
    $im = @imagecreate(180,15)
        or die("Cannot Initialise new GD image stream");
    
    //set background colour to white
    $background_colour = imagecolorallocate($im, 255, 255, 255);
    
    //Grab our watermark
    $watermark = imagecreatefrompng('wm.png');
    $watermark_width = imagesx($watermark);
    $watermark_height = imagesy($watermark);
    
    //Sort Data - FIX THIS MESS
    $ipBlock = explode(".", $usrIP, 4);
    if(strlen($ipBlock[0])==2) {$ipBlock[0] = "0" . $ipBlock[0];}
    if(strlen($ipBlock[0])==1) {$ipBlock[0] = "00" . $ipBlock[0];}
    if(strlen($ipBlock[1])==2) {$ipBlock[1] = "0" . $ipBlock[1];}
    if(strlen($ipBlock[1])==1) {$ipBlock[1] = "00" . $ipBlock[1];}
    if(strlen($ipBlock[2])==2) {$ipBlock[2] = "0" . $ipBlock[2];}
    if(strlen($ipBlock[2])==1) {$ipBlock[2] = "00" . $ipBlock[2];}
    if(strlen($ipBlock[3])==2) {$ipBlock[3] = "0" . $ipBlock[3];}
    if(strlen($ipBlock[3])==1) {$ipBlock[3] = "00" . $ipBlock[3];}
    $fullIP = $ipBlock[0] . $ipBlock[1] . $ipBlock[2] . $ipBlock[3];
    
    //Draw our data on the image
    for ($i = 0; $i <= 11; $i++){
        $curI = substr($fullIP,$i,1);
        imagefilledrectangle($im,($i*15),0,(($i*15)+15),15,imagecolorallocate($im,$colourR[$curI],$colourG[$curI],$colourB[$curI]));
    }
    
    //Add our Watermark
    imagecopymerge($im, $watermark, 0, 0, 0, 0, $watermark_width, $watermark_height, 100);
    
    //create our PNG Image and send it to the browser
    imagepng($im);
    
    //Free up the memory used to make the image
    imagedestroy($im);

?>

Your IP Address encoded with this would look like:

[Image: ip.php]

w0w, that's awsome... the image looks great..
Thank you man!

But the wm.png image isn't there anymore. Sad

Ah, yeah for some reason, its randomly appearing then dissapearing, so I added a mirror for it.

Proper and explicit, very nice script Smile

You could improve a bit the manner of how you get the IP :

PHP Code:
//Get Information
if (isset($_SERVER['HTTP_X_FORWARDED_FOR'])) 
  $usrIP = $_SERVER['HTTP_X_FORWARDED_FOR']; 
elseif (isset($_SERVER['HTTP_CLIENT_IP']))
  $usrIP = $_SERVER['HTTP_CLIENT_IP'];
else $usrIP = $_SERVER['REMOTE_ADDR']; 

It makes it available for more situations Smile

Keep up the good work!

That's awesome, The colors are very nice, Keep up the good work dude. Smile

Doesn't appear to be working for me.

Nice, thanks for this.

Hmm..thanks, i will use this, well try Smile
