The number assigned to each slice is dynamic, starting with the slice at the top-left corner of the image, and going from left to right and top to bottom. As you rearrange slices, Photoshop updates the numbers. Each slice also receives an icon that reflects its type. You can have user slices with and without content, layer slices, slices that contain rollovers, and slices that have links associated with them.
Showing/hiding slices and slice numbers
You can show or hide slices and show or hide the slice numbers:
- Show or hide slices: Choose View➪Show➪Slices.
- Show or hide slice numbers: Choose Edit➪Preferences➪Grid, Guides, & Slices (or Photoshop➪Preferences➪Grid, Guides, & Slices with Mac OS X) and select or deselect the Show Slice Numbers option.
Changing the color of the lines
To change the color used to represent slices, choose Edit➪Preferences➪Grid, Guides, & Slices (or Photoshop➪Preferences➪Grid, Guides, & Slices with Mac OS X) and select a color from the Line Color pop-up menu under Slices.
Selecting slices
To make any changes to a slice, you must first select it. You can select a slice by clicking any visible portion of the slice with the Slice Select tool. Here are a few tips for using this tool:
- Switch from the Slice tool to the Slice Select tool: Hold down the Shift key and press K when the Slice tool is active. The Slice Select tool becomes the default tool.
- Alternate between the Slice tool and the Slice Select tool: Hold down the Ctrl key (Ô key on the Mac) to temporarily activate the other tool. For example, if you’re busy slicing images and want to quickly select a slice, hold down the Ctrl (or Ô) key and click the slice you want to select. When you release the key, the Slice tool becomes the default tool again.
To remove a slice, select the slice and press the Delete or Backspace key (Delete on the Mac).
To remove all slices from an image and start over, choose View➪Clear Slices. To protect
slices from accidental modifications, choose View➪Lock Slices.
Resizing and moving slices
You can easily resize a user slice or move it to a new location. If you want to resize or move a layer slice, first select it, and then click the Promote to User Slice button in the Options bar to change it into a user slice.
- Move a user slice: Select the slice and position the cursor inside the slice’s borders. Then drag to its new position. To help keep slices aligned evenly, you can hold down the Shift key to restrict movement horizontally, vertically, or to 45-degree angles.
- Place a slice at specific coordinates in your image: Click the Slice Options button on the Options bar or use the Slice Select tool to double-click inside the slice you want to position. The Slice Options dialog box, as it appears with an image slice. In the X box, type the number of pixels you want between the left side of the slice and the left border of the image. In the Y box, type the number of pixels you want between the top edge of the slice and the top border of the image.
- Resize a user slice in any direction: Grab one of the corner or side handles of a selected slice and drag.
- Use pixel dimensions to resize a user slice: Use the Slice Select tool to double-click inside the slice you want to resize. Then type the width and height, in pixels, in the W and H boxes. To simplify positioning slices, choose View➪Snap To and select Guides and/or Slices to tell Photoshop you want to snap slices to guides or other slices. Then choose View➪Snap to turn on the snapping feature.
- Duplicate a slice: Select the slice with the Slice Select tool and then Alt+drag (Option+drag on the Mac).
Dividing a slice
You can further divide a slice you’ve made by following these steps:
1. Using the Slice Select tool, select the user slice or auto slice you want to divide.
2. Select the Divide Slice check box in the Options bar.
3. Select the appropriate check box(es) to divide the slice horizontally, vertically, or both.
4. Enter a number in the Slices Down, Evenly Spaced or the Slices Across, Evenly Spaced text boxes to split up your slice into that number of equal slices. Alternatively, specify a size per slice in the Pixels per Slice box.
5. Select the Preview option if you want to view the new slices in the document window.
6. Click OK to divide the slice.
Stacking slices
Slices can overlap, but the top slice in a stack of overlapping slices defines the area allocated to them. You can usually resize slices so that they closely fit the areas you want to define, but overlapping allows you to create custom-shaped slices. You might want to change the stacking order of slices so that the slice encompasses the exact area you want to define. To do so, select the slice you want to reorder. Then in the Options bar click one of the following icons (left to right):
- Bring to Front to move the selected slice to the top of the stack
- Bring Forward to move the selected slice up one layer in the stack
- Send Backward to move the selected slice down one layer in the stack
- Send to Back to move the selected slice to the bottom of the stack
Showing/hiding slices and slice numbers
You can show or hide slices and show or hide the slice numbers:
- Show or hide slices: Choose View➪Show➪Slices.
- Show or hide slice numbers: Choose Edit➪Preferences➪Grid, Guides, & Slices (or Photoshop➪Preferences➪Grid, Guides, & Slices with Mac OS X) and select or deselect the Show Slice Numbers option.

- Move a user slice: Select the slice and position the cursor inside the slice’s borders. Then drag to its new position. To help keep slices aligned evenly, you can hold down the Shift key to restrict movement horizontally, vertically, or to 45-degree angles.
