Separate an Image into areas is it possible ?

Hi ,

I'm building a Metro UI c# app Windows 8.

I'm calling a webservice where I must download a picture and display it in my app.

I don't have a problem with that so I'm not asking for that code.

The scenario is as follows.

I must be able when I click on the picture in certain areas to display some information. Let's say that I have a spare part when I click in a specific are of the image I want to display the name of part. When I click in a different area inside the image to display something else(I know how to display things so let's not focus in there).

How do I do that (Kind like we have in the HTML areas)?

Do I need to use an image control load in there the downloaded picture and then what ?

I 'm ok as far it concerns the code part ,donwload and display in an Image control.

After that ? How can I implement the click part? Click in certain area (x,y) and display this and click in other area from inside the Image and display something different ?

Appreciate any guidance on this.

thank you
