I came across this Stack Overflow question today about replacing radio buttons with images, however the answers there didn't sit quite right with me. They were completely reliant on javascript, which was fine according to the OP, but I feel that javascript enhancements like this, especially when they deal with things which require user input, [...]

Despite the risk of joining in the echo chamber that I'm sure will start up very soon, I just wanted to write a little observation.
