Simple html/javascript game

I have game for you. I know you must be familiar with captchas. So this simple little game is just that. There will be a captcha the user has to solve it and when they do they see a smiley face, if they fail they see a sad face and then the SAME captcha reloads. Now here is the tricky/hard part. I want to 777 captchas made but each has to be a different html game file. I say hard because It will take a while to do so many but it would be same code just different images for the it. I will supply you with all the images of course. I will provide excel document that shows what are the correct images for each captcha
