Your IP Address in Colour

[Jamza]

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);

?>

Related file: wm.png (mirror)

Your IP Address encoded with this would look like:

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

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

[Jamza]

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

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

Proper and explicit, very nice script
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
Keep up the good work!

[immi]

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

[Omniscient]

Doesn't appear to be working for me.

[`Sharan]

Nice, thanks for this.

[Bartdevil]
