Well, you know that it is a postback if you save the fields inside the Click Event. Because that is what caused the postback.
When you wire up the event in the onclick="functionname" then when you click, it will fire that event and you can save the data at that time. I hope I understand what you meant.

If this is the case, is there a way I can identify that the event came from the Image button or the submit button?
