I have an image that I will be displaying on a page. I want to be able to first allow the user to click on parts of the image where they want a dot to appear, then I want to take the location of where they placed the dot and store it in a database. Can any one point me in the right direction?

I currently have a VB6 app where I am able to do this but the powers to be want me to develop a web app that will allow the user to do the same thing.

Any ideas?
