2. Tag! You’re It!
One of the central tasks of managing collections of images is tagging them with keywords so that you can find them in a hurry. While there are various high-end, media-management programs that do this sort of thing, if your needs are modest, Preview might be all you need. Any keywords added in Preview are recognized by other image-editing programs such as Photoshop and (more importantly) by Spotlight. Tag an image with a certain client, an event, or a subject; and instead of having to manually find all those images, you can use Spotlight to find them for you quickly and easily.
To add some keywords, choose Get Info (Command+I) from the Tools menu item. In the window that appears, click the Add button to type in one or more keywords and the Remove button to delete them. When you’re done, save the file. Spotlight itself is very useful for media browsing: Besides locating the files, you can also Command+drag them to create copies, double-click them to view them, or Control+click them to access a contextual menu of other useful functions and processes. One limitation of Preview is that you can’t add keywords to groups of files, just one file at a time.
