Optimizing Images for the Web
Viewing images during optimization
You use a dual image window to view both the
original and optimized images in the Save For Web
dialog box. This lets you compare the two images
and determine which optimization settings work
the best. If the entire image is not visible in the
view area, you can use the hand tool to bring
another area of the image into view. You can also
use the zoom tool to magnify or reduce the view.
To navigate in a view:
Select the hand tool ( ) in the Save For Web
1
dialog box, or hold down the spacebar.
Drag in the view area to pan over the image.
2
To zoom in or zoom out:
Do one of the following:
Select the zoom tool ( ) in the Save For Web
•
dialog box, and click in a view to zoom in.
Hold down Alt (Windows) or Option (Mac OS)
•
and click in a view to zoom out.
Choose a magnification level from the Zoom
•
menu or enter a value in the Zoom text box, then
press tab.
Viewing optimization information
The annotation area in the 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 select a modem speed in
the Preview pop-up menu.
To select a modem speed:
1 Click the triangle ( ) to the right of the
optimized image to view the Preview pop-up
menu.
2 Choose a modem speed: 14.4 Kbps Download
Rate, 28.8 Kbps Download Rate, 56.6 Kbps
Download Rate, 128 Kbps Download Rate, or 256
Kbps Download Rate.
When you change the modem speed, the estimated
download time in the annotation area is updated.
Adjusting color display for cross-platform
variations
How an image appears on different monitors is an
important consideration when optimizing the
image for the Web. In general, an image appears
darker on a Windows system than on a Mac OS
computer. You can simulate cross-platform display
differences in the Save For Web dialog box.
To adjust color display for cross-platform variations:
Click the triangle ( ) to the right of the
1
optimized image to view the Preview
pop-up menu.
Choose a display option:

Uncompensated Color (the default option) to
