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
Note: You can also link slices in the Photoshop Save for Web dialog box. (See
with slices in the Save for Web dialog box (Photoshop)" on page
To link slices:
1 Select two or more slices you want to link.
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.
2 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 multimedia 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 rectangular 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 Are created using 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.
