316 CHAPTER 12 Optimizing Images for the Web Viewing images during optimization In Photoshop, you must choose File > Save for Web to view and work with optimized images. In ImageReady, you can view and work with optimized images at any time in the document window. Choosing a display option Display options in Photoshop and ImageReady enable you to switch easily between optimized and original (non-optimized) versions of an image and view up to four versions of an optimized image simultaneously. To select a display option for viewing images: Click a tab at the top of the image: • Original to view the image with no optimization. • Optimized to view the image with the current optimization settings applied. • 2-Up to view two versions of the image side by side. • 4-Up to view four versions of the image side by side. Working in 2-Up and 4-Up view When you choose 2-Up or 4-Up view, Photoshop or ImageReady determines a layout for the images based on the aspect ratio (width/height ratio) of the image. Images can appear in vertical layout, horizontal layout, or 2 x 2 layout (two rows and two columns). 2 x 2 layout is available for 4-Up view only. You can select a version of the image in 2-Up or 4-Up view to apply new optimization settings. You can automatically repopulate 2-Up and 4-Up views-generate new optimized versions of the image based on the selected version. You can also revert an optimized version to the original version of the image. In ImageReady, you can change the default optimizations in Optimization Preferences. (See "Setting optimization preferences (ImageReady)" on page 345.) To select a view: Click the view you want to select. A black frame indicates the selected version. To repopulate optimized versions of an image in 2-Up or 4-Up view: 1 Select an optimized version of the image in the 2-Up or 4-Up view. 2 In the Optimize panel of the Save for Web dialog box (Photoshop) or the Optimize palette (ImageReady), select Repopulate Views from the menu. Photoshop and ImageReady generate smaller optimized versions of the image based on the optimization settings of the selected version. The selected version and the original version, if present, are not altered during repopulation. For this reason, the Repopulate Views option works with 2-Up view only if the original version of the image is not present.
