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 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. 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);


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

so, to use this script, type in
