I think he basically wants to prevent automated logins by creating an image based login where the surfer has to manually enter the number(s) in the image back into the form to verify it is infact a human.

Generate the number based image.
Generate a hash.
Put the hash in a hidden field
Display image

And on submiting
Verify the hash exists in the db, and that the number in the next field beside the hash is the same number which was entered in the form area.

(doesnt have to be used to stop a login but can be used to break any automated process)

I guess you've already found your help, but I just wanted to add that GD would be a better choice for that rather than the ImageMagicK.

What's GD?

You can find out about GD here
http://www.boutell.com/gd/
If your doing what notjoe was talking about, GD would be way better to make pics with in the program. Here is what I do in Perl.

Code:

#!/usr/bin/perl

use CGI;
use GD;
use String::CRC32;

# create a new image
$q = CGI->new();
$im = GD::Image->new(100,15);
$crc = crc32($q->remote_host());

# allocate some colors
$bg = $im->colorAllocate(96,128,160);
$white = $im->colorAllocate(255,255,255);

$im->transparent($bg);
$im->interlaced('true');
$im->string(gdGiantFont,0,0,$crc,$white);

print $q->header(-type=>'image/jpeg');
print $im->jpeg();

Doh, got to this thread too late. Yes, GD is what you want.

If you haven't already selected from the half dozen other posts above, give me a shout.
