Previewing images Click a tab at the top of the image area to select a display option:
Original to view the image with no optimization, Optimized to view the image with the
current optimization settings applied, 2-Up to view two versions of the image side by side,
or 4-Up to view four versions of the image side-by-side.
If the entire artwork is not visible in the Save for Web dialog box, you can use the hand tool
to bring another area into view. Select the hand tool (or hold down the spacebar), and
drag in the view area to pan over the image. You can also use the zoom tool to magnify or
reduce the view. Select the zoom tool , and click in a view to zoom in; hold down Alt
(Windows) or Option (Mac OS), and click in a view to zoom out. Alternatively, you can
specify a magnification level in the Zoom text box at the bottom of the Save for Web
dialog box.
Selecting a view Click a different pane in the Save for Web dialog box to select a new
view. If you’re working in 2-Up or 4-Up view, you must select a view before you apply
optimization settings. A black frame indicates which view is selected.
Viewing annotations The annotation area below each image Save for Web dialog box
provides valuable optimization information. The annotation for the original image shows
the file name and file size. The annotation for the optimized image shows the current
optimization options, the size of the optimized file, and the estimated download time
using the selected modem speed. You can choose a modem speed in the Preview
pop-up menu.
Working with slices during optimization
If your artwork contains multiple slices, you must specify the slices to be optimized. You
can apply optimization settings to additional slices by linking the slices. Linked slices in
GIF and PNG-8 format share a color palette and dither pattern to prevent the appearance
of seams between the slices.

Click the Toggle Slices Visibility button .
To select slices in the Save for Web dialog box:
1 Select the slice select tool .
2 Click a slice to select it. Shift-click or Shift-drag to select multiple slices.
Note: In the Save for Web dialog box, unselected slices are dimmed. This does not affect
the color of the final image.
To view slice options in the Save for Web dialog box:
Select the slice select tool, and double-click a slice. (See “
Choosing a slice type and setting
slice options” on page 294.)
To set options for multiple slices, double-click the last slice you select.
To link slices:
1 Select two or more slices that you want to link.
2 Choose Link Slices from the Optimize pop-up menu .
