I don't think you will really succeed because the image is usually very hard to OCR even with the best OCR package.
I've tried that with the images used by Yahoo and I've succeeded only once, but I've tried for tens of times. This is a real problem for me because I am blind, and ... But I would also be interested if there is a Perl module or free program that can be used for OCR.

Recently the company introduced a random number generator that the user has to confirm with when submitting the form. Their first attempt at this was with an applet that took a number hashed via XOR and left 0 padded it. Then they compared the number they started with with the reverse operation on the server side sticking the original number in the session. Anyway, this was all pretty easy to work around because 1. You could parse their HTML code to get the number 2. Debytecompile their applet code to see what the hash value you need to emulate in perl was. Now they've gotten creative even more and I think I'm stumped at least for now. They are now presenting the number as a series of gifs with cryptic urls for each digit. Now you expect them to eventually take it one step further and create one gif with one url and remove any information still left in the digit urls but they haven't gone this far yet. This is all to eliminate spammers automating the sending of SMS messages to their customers. I simply use this a personal email notification service and I think I'm out of the game as the only way to get around this is to OCR their image to get the number. Is there any open source code that can OCR an image that's clearly a digit? Has anybody seen schemes like this one employed before to avoid "automated form submissions?"
