Instead of driving to and from the photo processing shop, you take some time to organize your photos on your computer.

You unload your photos from your camera onto your computer, then empty the camera so you can snap more shots. I typically put each download set into a separate directory file folder under MyPhotos, and name it with the date and an added word or two like: MyPhotos2010.11.1.halloween

You can then uses software to review your photos, delete the poor shots, rotate any that are sideways, and even print a few of your favorites.
There is plenty of free software on the web to help manage your photos. You can crop your photos, brighten or darken those with a slightly incorrect exposure, and even eliminate red-eye.

I recommend using Google’s Picasa program to easily manage your photo library:

You want to have a good backup system in place so you don’t lose your electronic photo library.  Check out my thoughts on backing up your computer.
