Specifying image map options
You can specify a name, a URL, a target frame, and Alt text for an image map area in the Image Map palette.
To display the Image Map palette:
Choose Window > Image Map, or click the palette button 
on the right side of the options bar for the Image Map Select tool 
.
To change the name of an image map area:
- Select an image map area.
- In the Image Map palette, enter a new name in the Name text box.
To specify link options for an image map area:
- Select an image map area.
- In the Image Map palette, enter a URL for the link, or choose a previously created URL from the URL pop-up menu. You can enter a relative URL or an absolute URL. If you enter a n absolute URL, be sure to include the proper protocol (for example, enter http://www.adobe.com, not www.adobe.com for an HTML link). For more information on using relative URLs and full URLs, see an HTML reference (either printed or on the Web).
- In the Image Map palette, enter the name of a target frame in the Target text box, or choose an option from the pop-up menu. A frame name must match a frame previously defined in the HTML file for the document. When a user clicks the link, the specified file displays in the new frame:
- _blank to display the linked file in a new window, leaving the original browser window open.
- _self to display the linked file in the same frame as the original file.
- _parent to display the linked file in its own original parent frameset. Use this option if the HTML document contains frames and the current frame is a child. The linked file displays in the current parent frame.
- _top to replace the entire browser window with the linked file, removing all current frames.
- In the Image Map palette, enter text for an Alt tag in the Alt text box. The Alt text appears in place of the image map area in nongraphical browsers. In many browsers, it also appears if the user positions the mouse over the image map area.
Note: For more information on frames, see an HTML reference (either printed or on the Web).
