Create image slices exactly the same size

To create multiple slices in Photoshop that are exactly the same size, draw one slice that encompasses the full width you’d like all the slices to take up, switch to the Slice Select tool, and then click the Divide Slice button in the Options Bar and choose your options in the resulting dialog. This tip comes in handy when you’re working on a navigation bar for a Web site. You could use guides and drag the slices with the Slice tool by hand, but this is much easier and more accurate.
