Designing Web Pages
_top to replace the entire browser window with
the linked file, removing all current frames.
Note:
For more information on frames, see an
HTML reference (either printed or on the Web).
4
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 most browsers, it also appears if the user
positions the mouse over the image map area.
Selecting an image map type
(ImageReady)
ImageReady can create client-side and server-side
image maps. In client-side image maps, the links
are interpreted by the browser itself. In server-side
image maps, the links are interpreted by the server.
Because client-side image maps don’t need to
contact the server to function, they are often
significantly faster to navigate. By default,
ImageReady saves image maps as client-side
image maps.
Important:
Server-side image maps do not work in
images that have multiple slices.
You select an image map type in the Output
Settings dialog box. (See “Setting HTML output
options” on page 349.) If you select a server-side
image map, ImageReady generates a separate map
file based on the server option you select. However,
you’ll need to update the path to the map file in
your HTML file.
Working with rollovers
(ImageReady)
You use the Rollover palette, in conjunction with
the Layers palette, to add rollover effects to a Web
page. You can display an animation as a rollover
state, or you can create secondary rollovers in
which moving a mouse over one area causes an
image change in another area. ImageReady adds
JavaScript code to the resulting HTML file to
specify rollover states.
Note:
When working with rollovers, it is important
to preview images in a Web browser to ensure your
document will function correctly for Web users.
Also remember that image appearance will vary on
different operating systems.
About rollovers
A
rollover
is a Web effect in which different states
of an image appear when a viewer performs a
mouse action—such as rolling or clicking—
over an area of the Web page. A
state
is defined by
a specific configuration of the Layers palette,
including layer location, styles, and other
formatting options.
You use a slice or image map area to define the
active area for a rollover. By default, every slice or
image map area has one state—the Normal state.
(The Normal state corresponds to the appearance
of an image when it is first loaded into a Web
browser and no rollover effects have occurred.)
When you add a new state to the rollover, you
capture a snapshot of the slice or image map area
