===== Display the Slice Options dialog box =====
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.

Note: Setting options for an auto slice promotes the slice to a user slice.
