Learn how to use image maps in Dreamweaver to create interactive hotspots for your web site.
An image map is an image that has been divided into regions called hotspots; when a user clicks a hotspot, an action occurs (for example, a new file opens).
Client-side image maps store the hypertext link information in the HTML document—not in a separate map file as server-side image maps do. When a site visitor clicks a hotspot in the image, the associated URL is sent directly to the server. This makes client-side image maps faster than server-side image maps, because the server does not need to interpret where the visitor clicked.
Dreamweaver does not alter references to server-side image maps in existing documents; you can use both client-side image maps and server-side image maps in the same document. However, browsers that support both types of image maps give priority to client-side image maps. To include a server-side image map in a document, you must write the appropriate HTML code.
To use hotspots in Dreamweaver, you have to be in design view.
When you insert a client-side image map, you create a hotspot area and then define a link that opens when a user clicks the hotspot area.
You can create multiple hotspot areas, but they are part of the same image map.
In the Map field, enter a unique name for the image map. If you are using multiple image maps in the same document, make sure each map has a unique name.
Select the circle tool and drag the pointer over the image to create a circular hotspot.
Select the rectangle tool and drag the pointer over the image to create a rectangular hotspot.
Select the polygon tool and define an irregularly shaped hotspot by clicking once for each corner point. Click the arrow tool to close the shape.
After you create the hotspot, the hotspot Property inspector appears.
In the Link field, click the folder icon to browse to and select the file you want to open when the user clicks the hotspot, or type the path.
In the Target drop-down list, select the window in which the file should open or type its name.
The names of all the frames you’ve named in the current document appear in the pop‑up list. If you specify a frame that doesn’t exist, the linked page loads into a new window that has the name you specified. You can also select from the following reserved target names:
The target option isn’t available until the selected hotspot contains a link.
You can easily edit the hotspots you create in an image map. You can move a hotspot area, resize hotspots, or move a hotspot forward or back in an absolutely-positioned element (AP element).
You can also copy an image with hotspots from one document to another, or copy one or more hotspots from an image and paste them on another image; hotspots associated with the image are also copied to the new document.
Shift-click the other hotspots you want to select.
Press Control+A (Windows) or Command+A (Macintosh) to select all of the hotspots.
Drag the hotspot to a new area.
Use the Control + arrow keys to move a hotspot by 10 pixels in the selected direction.
