About 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.
To create an animated GIF file, you work with layers. Each layer becomes a frame when Photoshop Elements
generates an optimized animation.
You can open an existing animated GIF file using the Open command from the Editor. For each frame in the file,
Photoshop Elements creates a layer. To view a specific frame in the document window, make the layer for that frame
visible in the Layers palette, and hide other layers.
Images in separate layers can be sequenced together to create an animation

To apply a preset optimization setting
You can quickly and easily optimize an image for the web by choosing a predefined optimization setting, called a
preset, from the Preset menu near the upper right corner of the Save For Web dialog box. Presets are tailored to meet
the optimization needs of different types of images.
The name of each preset reflects its file format and quality level. For example, choose JPEG High to optimize an
image in JPEG format with High image quality and low compression. Choose GIF 32 Dithered to optimize an image
in GIF format, reduce the number of colors to 32, and apply dithering.
In the Save For Web dialog box, choose a setting name from the Preset menu, and then click OK.

In the Save Optimized As dialog box, type a file name and click Save.

Note: If you change the options in a preset, the Preset menu displays the word "Custom". You cannot save a custom
setting; however, the current settings appear in the Save For Web dialog box the next time you display it.
To optimize as JPEG
JPEG is the standard format for compressing photographs.
In the Editor, open an image and choose File > Save For Web.
