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:
1
Select the hand tool ( ) in the Save For Web 
dialog box, or hold down the spacebar.
2
Drag in the view area to pan over the image.
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:
1
Click the triangle (
) to the right of the 
optimized image to view the Preview 
pop-up menu.
2
Choose a display option:
Uncompensated Color (the default option) to 
view the image with no color adjustment.
