The image map formats allows users to select an image and draw circular, rectangular, or polygonal hotspots on the image.
Coordinates are created automatically for each hotspot you add. A URL can be defined (specifying whether the link contains the root URL or not) and you can move the hotspots you have created by selecting and dragging. Additionally, you can copy a hotspot by selecting it and holding down your CTRL key and then dragging. When you release you will see a copy of the hotspot.
The first set of numbers at the top right show your cursor location or dragged shape coordinates and the small triangle at the right and additional numbers shows the size of your created shape or the difference in coordinates from where you have dragged.
Note: The image map asset functions slightly different in IE in that you cannot move and copy as described above.
