Is it possible to write a some text to the image and save it to other
name useing GD library and functions ?

If yes can you tell me which function I gotta use maybe same samples ?

I was trying using this script

<?php

srand((double)microtime()*1234567); // Start the random gizmo
$image = imagecreatefromgif("google.gif"); // Get a background

$font =
"/opt/sun-jdk-1.5.0.10/jre/lib/fonts/LucidaTypewriterRegular.ttf"; //
Get a font

$textcolor = imagecolorallocate($image,0,0,0); // Set text color

$text1 = "FR. 4/23"; // Here is our text

imagefttext($image, 50, 0, 20, 50, $textcolor, $font, $text1); // Write
the text with a font

header("Content-type: image/jpeg"); // Its a JPEG
imagegif($image,'',90); // Zap it to the browser
imagedestroy($image); // Memory Freeupage

?>

but it only write a text in header actually not saving into image.

Thank You for help

i wrote this app last year
http://www.secretsparklegram.com/
it's for cell phones, but the idea is the same adding text over graphics and having php create
images. if this is similar to what you want, i can post code that adds text over images. You'll
have to adapt your to your needs most likely.

We have some working example using PHP at:
http://www.thebook-demo.com/php/

It is CRUCIAL that you don't output any blank lines
before the "Content-type" - that often causes problems..

The source is:
<?
Header("Content-type: image/png");
// note - must use the absolute font path
// be careful about blank lines in your code which will output a blank and confuse browser
$text = "This is a PHP Button";
$font = "/pub/comwww/thebook-demo/php/gd/fonts/arial.ttf";
if(!isset($s)) $s=11;
$size = imagettfbbox($s,0,$font,$text);
$dx = abs($size[2]-$size[0]);
$dy = abs($size[5]-$size[3]);
$xpad=19;
$ypad=19;
$im = imagecreate($dx+$xpad,$dy+$ypad);
$blue = ImageColorAllocate($im, 0x2c,0x6D,0xAF);
$black = ImageColorAllocate($im, 0,0,0);
$white = ImageColorAllocate($im, 255,255,255);
ImageRectangle($im,0,0,$dx+$xpad-1,$dy+$ypad-1,$black);
ImageRectangle($im,0,0,$dx+$xpad,$dy+$yp
ad,$white);
ImageTTFText($im, $s, 0, (int)($xpad/2)+1, $dy+(int)($ypad/2), $black, "$font", $text);
ImageTTFText($im, $s, 0, (int)($xpad/2), $dy+(int)($ypad/2)-1, $white, "$font", $text);
Imagepng($im);
ImageDestroy($im);
?>
