The Save For Web dialog box offers several important options
for optimization and preview:
•
Tools. If you can't see the entire image, you can use the
Zoom tool to make the image more visible. Additionally,
you can use the Hand tool (or hold down the spacebar) to
drag and navigate around the image. Alternatively, you
can click the Zoom Level menu in the lower-left corner and
choose a magnification level.
•
optimization tabs. By clicking the four tabs at the top,
you can choose to view the Original image, an Optimized
view, 2-Up for two versions of the image side by side, or
4-Up for four versions of the image side by side. Being
able to compare optimized images helps you choose the
right format and compression settings. For this image,
choose 2-Up.
•
image optimization info. The area
below each image in the Save For Web
dialog box gives you optimization infor-
mation. You can see the current optimi-
zation applied, the projected file size, and the estimated
download time based on a selected modem connection
speed. Choose the JPEG High preset, and you'll notice
that the file has been reduced from 32 MB to 1.055 MB
(a significant savings). However, the download time is 196
seconds on a 56K modem (you can right-click the time to
choose another speed).

The first area to tackle is the actual image size in pixels. In
the Image Size field you'll see that the image is more than
4,000 pixels tall (which is much taller than a typical web page
that can be displayed on most monitors). Type in a Height
of 600 pixels, so the image can integrate easily into the web
page (even with a screen resolution of 1024 × 768, a height
of 600 would allow the image to display without scrolling up
and down). Press the Tab key to exit the file and apply the
resize value.

The file size has been significantly reduced, but it's difficult to
see the effects of the compression. Set the image magnification
view to 100%.
