Create image From GIF

[CaTaLinU]

I want to be an animated image
and on that , in the .php file to set a text to be on that image

something like createimagefrompng

<?php

header('Content-Type: image/gif');
$newimg = imagecreatetruecolor( 450, 95 ) or die ( 'GD Library not available atm.' );
$cs = ImageCreateFromgif("boobs.gif");
$culoare_text_alb = imagecolorallocate($newimg, 255, 255, 255);

imagettftext($cs,10,0,5,14,$culoare_text_user,"fonts/font_captcha.ttf","Text1");
imagettftext($cs,7,0,190,14,$culoare_text_rang,"fonts/font_captcha.ttf","Text1");
imagegif($cs);
imagedestroy($cs);

?>
