You think I'm going to put together a form that does captcha's just to make your life easy?
Really not going to happen.
I don't know how anyone else does it but I guess you will need a table that stores images and the text for the image.
Then you can have a form that picks records at random from that table and displays the image and checks the entered text.
It's not exactly difficult - the only awkward bit is getting enough images to populate the table with.

I can't think of any way of coding a process to work out what the image says. I'm not saying it's impossible but I wouldn't know where to start.
You need to build a list of images and the text they correspond to manually.
Once you've got that list in a table the rest is very easy but I can't see any way to automate building the list in the first place.
EDIT: changed possible to impossible.
