Request for a small web based RPG bot

[TreZide]

There is a small web based RPG that I play. It has a battle system that involves clicking an attack button, continue button, restart battle button, and leave battle button(If you die before you finish, so you can hit the restart button). The problem is that every so often a captcha has to be solved. The captchas from my knowledge are selected from a 500 image database. I've taken all the images already - I just have no idea how to make something to compare the captchas to the captcha periodically presented and automatically answer it whilst instantly going back to battling afterward.

Provided I can give up the images, would anyone be willing to make/help me create(what I believe to be) a rather simple bot to make?
