Convert String to Image

In facebook.com we see a nice thing,that is when u try to edit ur profile the e-mail address becomes image ! I mean u just type string and that becomes image.Here is the code which can convert string into image.

$date = ‘Raquibul Islam’;

$img = imagecreatetruecolor(100,25);
$bgcol = imagecolorallocate($img,255,255,255);
$hatcol = imagecolorallocate($img,rand(128,255),rand(128,255),rand(128,255));
$headcol = imagecolorallocate($img,255,225,205);
$bodycol = imagecolorallocate($img,0,0,0);
$eyecol = imagecolorallocate($img,rand(100,200),rand(0,128),rand(128,255));
$mouthcol = imagecolorallocate($img,rand(128,255),0,0);
imagefill($img,0,0,$bgcol);
imagestring($img,2,8,4,$date,$bodycol);
imagesetthickness($img,1);
imagerectangle($img,0,0,99,24,$bodycol);
header(“Content-type: image/png”);
imagepng($img);
imagedestroy($img);

Just copy the code and paste it into a .php file and run it.The string from $data will represent as an image.
