If you've had a digital camera for any length of time, by now you have thousands--maybe even tens of thousands--of digital pictures of anything and everything. And if you're like most people you've cheerfully imported them into photo management software of some sort. Maybe it's something like NikonView that came with your camera or maybe it's the copy of Photoshop Elements that came pre-installed on your hard drive. Perhaps it's Picasa. If you're on a Mac it's almost certainly iPhoto. Or maybe you're a pro, or just really into digital photography, and you hopped on one of the Adobe Lightroom betas or shelled out some cash for something like ACDSee, iView, or Aperture.

Whatever you're doing it's probably time to stop. Photo gallery and management software is a wonderful way to arrange and display pictures you want to use for something. Most of of the time, the "something" is printing, displaying on screen as a slideshow or screensaver, or uploading to a photo sharing service like Flickr. For most people, that describes a very small fraction of the pictures they take. The rest just sit around in the photo library collecting dust and causing trouble, mostly in the form of slowdowns. Your library has to load all those thumbnails every time you open it, whether you ever look at the pictures or not. When you add new photos, the software has to scan the pictures, add the appropriate information to its database, create thumbnails, probably copy the images to its own directory, and sometimes even convert the images to its native format. And again, it has to do that even if you never even look at the image.

That takes time. Often it takes a lot of time, and for nine tenths of digital photos, it's wasted time.

On the other hand, you don't really want to just delete all those other pictures. The sheer quantity is part of the fun of digital photography, right? And you never know when some of those truly horrible shots might come in handy. Maybe that horrible shot of your uncle making that silly face will turn out to be the only picture of him anyone can find for a scrapbook later. Maybe you'll want something in the background of a blurry shot of a friend for reference later. Who knows? But since storage is cheap these days, there's no reason to delete all that stuff, even if you don't want it clogging up your workflow.
