I used to have literally thousands and thousands. But they were all in iPhoto. Then one day I had a complete hard drive failure and lost almost all of them that I didn’t have saved elsewhere. Now I have maybe 100? The HD failure happened well after our kid was born and she wasn’t feeling like much of an exhibitionist anymore, and we’ve barely taken pictures since. It’s so fucking depressing.
Now the ones I still have, I have like 4 different back-ups saved, just in case. Don’t be like me, folks, if you have pics, create backups on different drives. You never know when a drive will just fail and you’ll lose everything.
