There's a class in www.phpclasses.org which help you generate such images, I've no idea how good it is. It's pretty straightforward to write your own using the image functions: 1) create a new image 2) set a background colour 3) create some random characters, using random fonts, random colour (limit the set of colours to choose from so it doesn't disappear into the background), and small amount of random rotation 4) for good measure sprinkle the image liberally with randomly coloured pixels. -- Jason Wong -> Gremlins Associates -> www.gremlins.biz Open Source Software Systems Integrators * Web Design & Hosting * Internet & Intranet Applications Development * ------------------------------------------ Search the list archives before you post http://marc.theaimsgroup.com/?l=php-general ------------------------------------------ /* Question: Is it better to abide by the rules until they're changed or help speed the change by breaking them? */ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
