You can enable the option in Preferences or in the Save As dialog box. Because previews increase both file size and
the time it takes to save the document, you may prefer to enable the option on demand using the Save As dialog box.
Note: (Mac OS) A low-resolution PICT preview is also created for viewing in the Finder.

About metadata
Metadata is a set of standardized information about a file, such as author name, resolution, color space, copyright,
and keywords applied to it. For example, most digital cameras attach some basic information to an image file, such
as height, width, file format, and time the image was taken. You can use metadata to streamline your workflow and
organize your files.
About the XMP standard
Metadata information is stored using the Extensible Metadata Platform (XMP) standard, on which Adobe Bridge,
Adobe Illustrator, Adobe InDesign, and Adobe Photoshop are built. Adjustments made to images with Photoshop®
Camera Raw are stored as XMP metadata. XMP is built on XML, and in most cases the metadata is stored in the file.
If it isn’t possible to store the information in the file, metadata is stored in a separate file called a sidecar file. XMP
facilitates the exchange of metadata between Adobe applications and across publishing workflows. For example, you
can save metadata from one file as a template, and then import the metadata into other files.
Metadata that is stored in other formats, such as Exif, IPTC (IIM), GPS, and TIFF, is synchronized and described
with XMP so that it can be more easily viewed and managed. Other applications and features (for example, Adobe
Version Cue) also use XMP to communicate and store information such as version comments, which you can search
using Bridge.
In most cases the metadata remains with the file even when the file format changes, for example, from PSD to JPG.
Metadata is also retained when files are placed in an Adobe document or project.
You can use the XMP Software Development Kit to customize the creation, processing, and interchange of metadata.
For example, you can use the XMP SDK to add fields to the File Info dialog box. For more information on XMP and
the XMP SDK, visit the Adobe website.
