We all take and store hundred's of digital photo's of our display, as well as everything else in our lives.
My tip, is tag the photo's.
adding a tag, you can make quick reference to it later.
It doesn't matter what program you use, as they all seem to have the ability. If your not sure your program does, download Picasa. It is free.
You can tag people as well as objects, or events.
Do this, and then you can find that one picture that you have been searching for much faster.
So, I tag (Christmas, Lights, Garage, How-to), as well as the people in the pics.
Just a tip.
