How to find out the co-ordinates when I click on a world map(Image)?

[Sunil Tiwari]

Hi,   I have a world map which is an image and the user can click on any of the continent. Once a particular continent is clicked, the world map must be replaced by that continent's map and so on..   Now, I have one image for each continent. The problem is how to know which continent was clicked upon in the world map?   Any Ideas?   Regards, Sunil
