Preview

Preview is Mac OS X’s built-in graphics viewer. When you double-click the icon of a graphics file whose “parent” the Mac can’t identify (maybe something you grabbed from a Web page or scanned in), Preview takes over. It handles the work of opening and displaying the image onscreen.

Preview works with pictures saved in a wide variety of formats, including JPEG, TIFF, GIF, and PICT, and less common formats like PNG, SGI, TGA, and MacPaint. Preview can even open complex Photoshop files and multipage PDF documents.

In the Finder, select all the images you’d like to see, and drag them en masse onto the Preview icon (either on the Dock or in your Applications folder), as shown in Figure 11-17.

Drag a group of related images onto the Preview icon, and you can easily browse them from a single image window.
