How Can I Find Click Points In An Image For Steganography

You are assuming a lot of knowledge on the part of the person who has to answer this question.
What is a click point in relation to Steganography? I'm not sure what that is. It is also not clear what you're really asking for. Mouse cursor location on an image? or is it a decryption algorithm to find the most likely changed values?
Anyway you need to think of a better question in order to get a useful answer.
