Open your image first.
Now, go over to your toolbars, and select the image mapping tool.

Now, go over to your image, and select (click down over area) of which you want image mapped.

Now, go over to the image map window (if it is not visible, go to the top tabs, click on
window>imagemap Now, where it says "url" paste in the url wanted, also type in your alt. (alt = the text that will appear when hovered over)

Okay, when you are all done imagemapping all the links, go to the top tabs, and choose "edit" "copy html code" and "for all slices" This will automatically copy the codes into your clipboard. Just paste it.

Oh, remember to change the <img src="something.jpg"> to a valid image url.
