Do one of the following:

• Double-click a slice with the Slice Select tool . (If the tool isn’t visible, hold down the Crop or Slice tool.)
• With the Slice Select tool active, click the Slice Options button  in the options bar. This method is not in the Save For Web & Devices dialog box.

Specify a slice content type

You can specify how the slice data appears in a web browser when exported with an HTML file. The available options vary according to the slice type you select.

• Image slices contain image data. This is the default content type.

• No Image slices let you create empty table cells that can be populated with text or a solid color. You can enter HTML text in a No Image slice. If you set the Text Is HTML option in the Save for Web & Devices dialog box, the text is interpreted as HTML when viewed in a browser. Slices of type No Image aren’t exported as images and can be previewed in a browser.

Rename a slice

As you add slices to an image, you may find it helpful to rename slices based on their content. By default, user slices are named according to the settings in the Output Settings dialog box.

Choose a background color for a slice

You can select a background color to fill the transparent area (for Image slices) or entire area (for No Image slices) of the slice.

Photoshop does not display the selected background color—you must preview the image in a browser to view the effect of selecting a background color.

Assign URL link information to an Image slice

Assigning a URL to a slice makes the entire slice area a link in the resulting web page. When a user clicks the link, the web browser navigates to the specified URL and target frame. This option is available only for Image slices.

Specify browser messages and Alt text

You can specify what messages appear in the browser. These options are available only for Image slices and appear only in exported HTML files.

Add HTML text to a slice

When you choose a slice of type No Image, you can enter text to be displayed in the slice area of the resulting web page. This can be plain text or text formatted with standard HTML tags. You can also select vertical and horizontal alignment options. For more information on specific HTML tags, see an HTML reference.

Photoshop does not display HTML text in the document window; you must use a web browser to preview the text. Be sure to preview HTML text in different browsers, with different browser settings, and on different operating systems to confirm that your text is displayed correctly on the web.
