Applying optimization settings

You use the Optimize panel in the Save for Web dialog box (Photoshop) and the Optimize palette (ImageReady) to set optimization options. If you're working in 2-Up or 4-Up mode, you can repopulate the views to automatically generate lower-quality versions of the image based on the selected settings.

To apply optimization settings:

1. Select a view to which you want to apply optimization settings.
2. If your artwork contains multiple slices, select one or more slices to which you want to apply the optimization settings. (See Working with slices in the Save for Web dialog box (Photoshop) and Selecting slices.)
3. Do one of the following:
• Choose a named optimization setting from the Preset menu. For information on creating custom named settings, see Saving and resetting optimization settings.
• Choose a file format from the File Format menu.
4. Set additional optimization options. The file format you chose in Step 3 determines which options are available to you.

For more information on specific optimization options, see Optimization options for GIF and PNG-8 formats, Optimization options for JPEG format, Optimization options for PNG-24 format, and Optimization options for WBMP format.

To apply optimization settings based on file size:

1. Choose Optimize to File Size from the Optimize pop-up menu (Photoshop) or the Optimize palette menu (ImageReady).
2. Choose a Start With option:
• Current Settings to use current optimization settings.
• Auto Select GIF/JPEG to automatically generate a GIF or JPEG file. (Photoshop or ImageReady selects GIF or JPEG format, depending on its analysis of colors in the image.)
3. Enter a value for file size.
4. In the Use area, choose which slices to affect: Current, Each, or Total of All Slices. Click OK.

To repopulate optimization settings:

1. Apply optimization settings to a view in 2-Up or 4-Up mode.
2. Choose Repopulate Views from the Optimize pop-up menu (Photoshop) or the Optimize palette menu (ImageReady).

The optimization settings for the selected view and the original view are not altered during repopulation.

To restore an optimized version of an image to the original version:

1. Select an optimized version of the image in 2-Up or 4-Up mode.
2. In the Optimize panel/palette, choose Original from the Settings pop-up menu.
