anyone got a working script for this? i can't seem to get anything working that i find when i search...

edit: i found a code to generate an image, and i use rand to generate text on it...

now when i press a submit button, how can i check if the generated text matches the textbox?

<?php
$my_img = imagecreate( 60, 20 );
$background = imagecolorallocate( $my_img, 0, 0, 255 );
$text_colour = imagecolorallocate( $my_img, 255, 255, 0 );
$line_colour = imagecolorallocate( $my_img, 128, 255, 0 );
$rand_string = rand(999999, 9999999);
imagestring( $my_img, 4, 1, 2, $rand_string,
  $text_colour );
imagesetthickness ( $my_img, 5 );
imageline( $my_img, 30, 45, 165, 45, 0);

header( "Content-type: image/png" );
imagepng( $my_img );
imagecolordeallocate( $line_color );
imagecolordeallocate( $text_color );
imagecolordeallocate( $background );
imagedestroy( $my_img );
?>

i belive i got 1 step further but 1 problem more...

<?php

//image.php
session_start(); 
$_SESSION['rand_string'] = $random;
$my_img = imagecreate( 60, 20 );
$background = imagecolorallocate( $my_img, 0, 0, 255 );
$text_colour = imagecolorallocate( $my_img, 255, 255, 0 );
$line_colour = imagecolorallocate( $my_img, 128, 255, 0 );
$rand_string = rand(999999, 9999999);
$random = $rand_string;

imagestring( $my_img, 4, 1, 2, $random,
  $text_colour );
  
imagesetthickness ( $my_img, 5 );
imageline( $my_img, 30, 45, 165, 45, 0);

header( "Content-type: image/png" );
imagepng( $my_img );
imagecolordeallocate( $line_color );
imagecolordeallocate( $text_color );
imagecolordeallocate( $background );
imagedestroy( $my_img );

?>

<?php
//index.php or whatever
session_start(); 
echo $_SESSION['rand_string']; //retrieve data
?>

<img src="image.php" width="60px" height="20px">

everything seems to work except that the random value isn't the same...

you're echoing out rand_string before it's set by image.php. of course it wouldn't be the same. you have to set it by calling image.php, and then echo it.

can you show some code, because i'm totally blank now..

edit: never mind i got it now. thank you
