Arranging user slices and layer-based slices
When slices overlap, the last slice you create is the top slice in the stacking order. You can change the stacking order to gain access to underlying slices. You can specify which slice is on the top and bottom of the stack and move slices up or down in the stacking order.
Note: You cannot arrange the stacking order of auto slices.
To change the stacking order of slices:
- Select a slice. In ImageReady, you can select multiple slices.
- Do one of the following:
- With the Slice Select tool active, click a stacking order option in the options bar: Bring to Front
, Bring Forward 
, Send Backward 
, or Send to Back 
. - (ImageReady) Choose Edit > Arrange Slices and choose a stacking order command from the submenu.
- (ImageReady) Drag the slice up or down in the Web Content palette. See Using the Web Content palette.
