Assuming you compiled PHP with GD support, you can use the GD2 functions.

ive looked into that but i cant find a function that will write text on a image, just to create a image with text

ive found what i want but i get a error, whats the full path to the font file ive tried this but i get that error.

$font = imagepsloadfont($_SERVER['DOCUMENT_ROOT'].'/font.pfm');

Fatal error: Call to undefined function imagepsloadfont() in /home/fhlinux159/p/ps3.gavssite.com/user/htdocs/test/test.php on line 11

Full Code

<?php
// Create image handle
$im = imagecreatefrompng($_SERVER['DOCUMENT_ROOT'].'/test/test.png');

// Allocate colors
$black = imagecolorallocate($im, 0, 0, 0);
$white = imagecolorallocate($im, 255, 255, 255);

// Load the PostScript Font
$font = imagepsloadfont($_SERVER['DOCUMENT_ROOT'].'/font.pfm');

// Write the font to the image
imagepstext($im, 'Sample text is simple', $font, 12, $black, $white, 50, 50);

// Output and free memory
header('Content-type: image/png');

imagepng($im);
imagedestroy($im);

please do not repost threads if you haven't had it resolved. we don't discourage bumping.

anyways, I think you should look at this link, since your error is with loading fonts

http://uk2.php.net/manual/en/function.imagepsloadfont.php

specifically this note:

Note: This function is only available if PHP is compiled using --with-t1lib[=DIR].

Did you in fact compile php with t1lib?
