Optimizing Images for the Web and E-mail
To preview browser dither:
Choose Browser Dither from the document panel
menu in the Save For Web dialog box. (To view the
menu, click the triangle near the upper right
corner of the document panel.)
To preview browser dither in a browser:
1
Set your computer’s color display to 8-bit color
(256 colors). See your computer operating
system’s documentation for information on
changing the color display.
2
Select a browser from the Preview pop-up
menu in the Save For Web dialog box.
Minimizing browser dither
Using colors in the Web palette ensures that colors
won’t dither when displayed on Windows or
Macintosh systems capable of displaying 256
colors. When creating an original image, you can
use the Color Picker to choose Web-safe colors.
(See “Using Web-safe colors” on page 132.)
Previewing an image in a
browser
You can preview an optimized image in any Web
browser installed on your system. The browser
preview displays the image with a caption listing
the image’s file type, pixel dimensions, file size,
compression specifications, and other HTML
information.
To preview an optimized image in a Web browser:
In the Save For Web dialog box, choose a browser
from the Preview In pop-up menu, or click the
browser icon to launch your default Web browser.
To add a browser to the Preview pop-up menu:
1
Create a shortcut (Windows) or alias (Mac OS)
for the browser you want to add to the menu. (For
more information on creating shortcuts or aliases,
see your operating system documentation.)
2
Drag the icon for the shortcut or alias into the
Preview In folder, located in the Helpers folder in
the Photoshop Elements program folder.
3
Restart Photoshop Elements.
Saving optimized images
You must save an optimized image before you can
use it on the Web.
To save an optimized image:
1
Apply optimization settings in the Save For Web
dialog box, and click OK. (See “Optimizing Web
images” on page 210.)
2
Type a filename, and choose a location for the
optimized file.
3
Click Save.
Creating animated GIFs
Some animations that you view in a Web browser
are called animated GIFs. Animated GIFs create
the illusion of movement by displaying a sequence
of images, or frames, over time. Photoshop
Elements provides a powerful, easy way to create
animated GIFs from a multiple-layer image.
