Distributing user slices (ImageReady)
In ImageReady, you can distribute user slices evenly along the vertical or horizontal axis. Distributing user slices can eliminate unneeded auto slices and generate a smaller, more efficient HTML file.
Note: To distribute layer-based slices, distribute the contents of the layers. (See Aligning layers.)
To distribute user slices:
- Select three or more user slices you want to distribute.
- Do one of the following:
- With the Slice Select tool active, click a distribution option in the options bar: Distribute Top Edges
, Distribute Vertical Centers 
, Distribute Bottom Edges 
, Distribute Left Edges 
, Distribute Horizontal Centers 
, or Distribute Right Edges 
. - Choose Edit > Distribute Slices, and choose a command from the submenu.
