Designing Web Pages
Linked slices in GIF and PNG-8 format share a
color palette and dither pattern. The dither pattern
is applied across adjacent slice boundaries to
prevent the appearance of seams between the
slices. (See "Previewing and controlling dithering"
on page 341.)
To link slices:
Select two or more slices you want to link.
1
Note: If the first slice you select is a user-slice,
any auto-slices you link to the first slice become
user-slices. If the first slice you select is an
auto-slice, any user-slices you select are linked
to the auto-slice group.
Choose Slices > Link Slices.

Each linked set of user-slices is assigned a different
color for the slice display graphics in the upper left
corner of the slice. This helps to identify all the
slices in one set.
To unlink user-slices:
Do one of the following:
To unlink a user-slice, select the slice, and then
•
choose Slices > Unlink Slices.
To unlink all user-slices in a set, select a slice in
•
the set, and choose Slices > Unlink Set.
To unlink all user-slices in an image,
•
choose Slices > Unlink All.
Creating and viewing image
maps (ImageReady)
Image maps enable you to link an area of an image
to a URL. You can set up multiple linked areas—
called image map areas—in an image, with links to
text files; other images; audio, video, or multi-
media files; other pages in the Web site; or other
Web sites. You can also create rollover effects in
image map areas.
The main difference between using image maps
and using slices to create links is in how the source
image is exported as a Web page. Using image
maps keeps the exported image intact as a single
file, while using slices causes the image to be
exported as a separate file. Another difference
between image maps and slices is that image maps
enable you to link circular, polygonal, or rectan-
gular areas in an image, while slices enable you to
link only rectangular areas. If you need to link only
rectangular areas, using slices may be preferable to
using an image map.
Note: To avoid unexpected results, do not create
image map areas in slices that contain URL links—
either the image map links or the slice links may be
ignored in some browsers.
Creating image maps
You can create image map areas using an image
map tool or a layer.
Tool-based image map areas
an image map tool—you drag in the image to
define the image map area. You can view and set
options for tool-based image maps in the Image
Map palette.
