So basically what you want to do is generate a pseudorandom word as a string and then use a php graphics library to generate an image that contains the word from that string in it?

Sounds kind of cool actually. I can probably do the first part but I don't know PHP's graphics libraries. They are documented though, have you tried looking around on http://www.php.net/ to see if you can find some fucntions for generating images on the fly?

here is the php graphic script i use to generate images on the fly. php.net has tons more!!

in this php file you could create an algorithm that generates a random sequence of letters, encrypt it, and then have the image decrypt word and print?? if that makes any sense.

<?

header ("Content-type: image/png");
$im = @ImageCreate (400, 75) or die ("Cannot Initialize new GD image stream");
$input = $_GET["input"];
$font = "/usr/X11R6/lib/X11/fonts/drakfont/ttf/sylfaen.ttf";
$background_color = ImageColorAllocate ($im, 255, 255, 255);
$text_color = ImageColorAllocate ($im, 233, 14, 91);
ImageTTFText($im, 60, 0, 10, 55, $text_color, $font, $input);
Imagepng ($im);
Imagedestroy($im);

?>

//?input=
//and u might want to change the font location to suit ur needs.

so, to use this script, type in

filename.php?input=text
