On the asset-based navigation in SPD 2010, you’ll need to navigate to an object that will allow you to create an HTML file in it. Here I’m using Site Pages, but you could also select All Files. You probably want to save it somewhere so you can modify it later, if need be.
Open the file (Untitled_1.html) for editing.
Delete the HTML that came with the new page.
Paste your image into the page.
Click on the map image and then select Format under Picture Tools. You’ll now have access to the Hotspot tool. Select either the Polygonal, Rectangular or Circular Hotspot drawing tool.
Using your coloring skills you learned in Kindergarten, trace each of the areas you want to hotspot.
When you close the polygon, you’ll get a dialog where you can enter the address that the hotspot is linked to.
Copy all the source to the clipboard…
…and paste it into the HTML view of a content editor web part.
You should see it displayed with the regions visible.
The finished product. Hovering over an area will give you "the hand" and clicking will take you to your hyperlink.
