Try:
$('.image').on('contextmenu', function (e) {
console.log(e.pageX),
console.log(e.pageY);
});
Context menu is the event for right click. Notice that you need either a '.' or a '#' before the text in the selector, or if you want it to apply to all image tags, then $('img')...
If you want to explore what's in an event, just use console.log(e) to have a browse around what you can garner from an event.
