Previews option in the Preferences dialog box.
(See “Setting preferences for saving files” on

preview options:
• Icon to use the preview as a file icon on the
desktop.

applications that can only open low-resolution
Photoshop Elements images.
• Macintosh Thumbnail to display the preview in
the Open dialog box.

display on Windows systems. Keep in mind that
Windows thumbnails increase the size of files as
delivered by Web servers.

extension for the selected file format. Select

About File Extensions Unix file servers are often
used to help send information over networks and
the Internet. Some of these Unix servers do not
recognize uppercase extension. To make sure your
images arrive at their destinations, use lower case
extensions.
Saving images in different file
formats
Different file formats cater to the needs of different
applications. The file format you choose depends
on the content of your image and how you plan to
use it. For example, you’re saving an image for use
on the Web, you should choose JPEG, GIF, or PNG
format.
You can save individual images in different
formats using File > Save As. You can convert
several images to the same file format, or the same
size and resolution, using the Batch command. See
“Using the Batch command” on page 234.
Until you’ve finished creating an image and have
decided how you want to use it, you should save
the image in Photoshop format (PSD) which is the
default file format. Saving your image in the
Photoshop format guarantees that you will be able
to access all of the image data when you reopen the
image.
If you choose a format that does not support all of
the data in an image, a warning appears at the
bottom of the Save As dialog box. If you see this
warning, save a copy of the file in Photoshop
format in order to support all of the image data.
To save an image in a different file format:
1 Choose File > Save As.
2 Specify a filename and location.
3 Choose a format from the following “Saving
in...” topics. With some image formats, a format-
specific dialog box appears after you click save.
