[jQuery] Get co-ordinates of click on image

[Michael Price]

Hi all,
Working on something for a client at the moment - they have a map and 
they want to pinpoint where on this map something is, and then store 
this in the database.

I'm thinking we put an image of the map in the admin area for them and 
they can click on it to set the co-ords, but I'm not sure how we'd fetch 
the co-ords of where they clicked? Just as X,Y pixels from the top left 
of the image, nowt too clever.

$("#map").click(function() {
    // WHAT GOES IN HERE?
}

Does anyone have any thoughts? All help much appreciated :)

Regards,
Michael Price
