Using the Layers palette, adjust the position, opacity, or layer effects of desired layers to create the
state of the final animation frame. Then choose Tween from the Animation palette menu to have
ImageReady generate intermediate frames from the starting and ending states you’ve defined.
Specify which layers and parameters to tween, enter the number of frames to generate, and click OK.
The Tween feature is useful for generating a variety of animations, such as making a single layer move
across the canvas or fade in or out.
Preview the animation
ImageReady offers the convenience of previewing your animation directly in the
image window. In the Animation palette, select the first animation frame and then click the Play
button (
) at the bottom of the palette.
Optimizing Web graphics
Optimization involves compressing the file size while optimizing the display quality of an image for
Web output. Photoshop and ImageReady let you optimize images in several Web file formats—
GIF, JPEG, and PNG—and provide you with both basic and advanced controls for fine-tuning the quality
and compression level of the optimization. Because live previews of the optimized image are regenerated
whenever an optimization setting is adjusted, you are free to experiment with different settings before
committing to final changes.
Compare original and optimized images
Choose File > Save for Web (Photoshop) or Window > Show
Optimize (ImageReady) to display the Web optimization settings. Click the Optimized tab above the
image preview (Photoshop) or in the image window (ImageReady) to display how the image will appear
on the Web using the current optimization settings. To display original and optimized previews side by
side, click the 2-Up tab.
Choose an optimization set
Photoshop and ImageReady provide a number of predefined optimization
settings. To apply a predefined optimization set, choose the desired set from the Settings menu in the Save
for Web dialog box (Photoshop) or the Optimize palette (ImageReady).
