Setting and viewing slice options
Setting slice options lets you specify how the slice data will appear in a Web browser when exported with an HTML file. The available options vary according to the application and the slice type you select. You can only set options for one slice at a time.
Note: Setting options for an auto slice promotes the slice to a user slice.
You specify slice options in the Slice Options dialog box (Photoshop) and the Slice palette (ImageReady).
To display the Slice Options dialog box (Photoshop):
- Double-click a slice with the Slice Select tool.
- With the Slice Select tool active, click the Slice Options button in the options bar. This method is available only in the main Photoshop application, not in the Photoshop Save for Web dialog box.
Do one of the following:
To display the Slice palette (ImageReady):
Choose Window > Slice, or select the Slice Select tool and click the palette button 
in the options bar.
