Sorry, can you describe with a concrete example what bots achieve by
printing a string into an image. Would that be a pre-existing image on the

It is not something new, you might have seen this before. The website
display an image, and a form. The user has to look the image and write
in the form what is drawn in the image. Since bots has problems to
read images, they can't enter the website.
Here is an example :
Go to http://www.paypal.com/
Click on the image 'Sign Up Now' then the button 'Continue'
Then, on the very bottom, you see an image with letters and digits on
it. To sign a new account, you have to write in the text box what is
written on the image.
This is what SW2LetterWarper is about
