Anyone know were i can get something like this?

[Jona]

It's just a generated image (imagecreate() (http://us3.php.net/manual/en/function.imagecreate.php)), with some grid lines (imageline() (http://php.net/imageline)), and a font with random letters/numbers (defined in the file including the PHP file that generates the image so that the script can validate it but avoid being hacked).

actually i was wanting it to prevent bots from filling out my forms.

That's what I meant. If you used, say, <img src="number.php?numbers=AFD12"> the bots could figure it out, so you'd just use number.php after defining a global variable... Right? Come to think of it, I could be wrong, but I think that'd be a good way to do it...

Yea, but do you know were i can get a script to make that image, and the text field?

[Jona]

Try http://hotscripts.com/ they have a lot of good scripts there. You also could try the PHP Resource Index (http://php.resourceindex.com/).

contact your host and make sure they have the gd library enabled for php... It's something you change in the php.ini file.

That's weird because it seems like every host has that enabled......

maybe its because the page has a .html extension and you need a .php extension? but idk as i have not worked with that script

[Johnathan808]

Actually it was because gd library was not enabled in php.ini. I got the script to work. Thanks to all that helped me!
