Client
We can link different parts of an image to different pages, which are called client-side image maps.
Note that the Image Properties panel extension mode has a map at the bottom left, which is used for client-side image mapping. Then you can fill in your name for this mapping, if not fill in, then Dreamweaver automatically add a name. The map has three icons, from left to right, to intercept rectangles, to intercept circles, and to intercept irregular graphics.
Mouse click on an appropriate icon, you can select a region of the mouse image. You can use the arrows on your keyboard to adjust when the mouse-drawn marquee and target do not coincide.
After you select and set up, the Properties panel is shown in the following image.

In addition to the map, there are link, alt, and target three items, which represent the same meaning as ordinary links, as long as the part of the image being intercepted as a separate page element. You can set hyperlinks to each area of the image that is intercepted.
