Aligning user slices (ImageReady)
In ImageReady, you can align user slices with the top, bottom, left, right, or middle. Aligning user slices can eliminate unneeded auto slices and generate a smaller, more efficient HTML file.
Note: To align layer-based slices, align the contents of the layers. (See Aligning layers.)
To align user slices:
- Select the user slices you want to align.
- Do one of the following:
- With the Slice Select tool active, click an alignment option in the options bar: Align Top Edges
, Align Vertical Centers 
, Align Bottom Edges 
, Align Left Edges 
, Align Horizontal Centers 
, or Align Right Edges 
. - Choose Edit > Align Slices, and choose a command from the submenu.
