So I have about 2.9 gigabytes of photographs I've taken on my computer, around 2000 pictures. I've kept all except the really, really crappy wrecked ones. What I plan to do is "cull the herd" monthly and drop it down a little, and mark really good ones, but I try and tend to keep almost all the digital photos I take. I use Google Picassa and have burned a backup DVD-RW disk with my pictures. I'm curious how much data other people have, and what they use to protect and archive their digital photos.
