Best way to get co-ordinates of a button?

[Dgriff]

Hi
I have created my website header and I need to create an image map to make my buttons clickable. What's the best way to get the exact co-ordinates of each button? Thanks.

If you go to window > Info then wherever you hover your mouse then it will show you your X and Y coordinates

Thanks Hoogle but I think I need 4 coordinates, 1 for each corner of the rectangle. Is there a way I can select an area by clicking and dragging and see the 4 coordinates then?

cant you just get the coordinates from each point
