I've been fretting about that too lately. Just got the Gun Safe app for my iPhone. It allows you to record all pertinent data including photographs in a password protected app. You can also email yourself a copy of the database for storage elsewhere. I'm not sure if it allows more than one photo per gun but I plan to do a separate photo gallery of each anyway, kept on multiple CDs. The app has an option to store info on the mfr.'s cloud server, but I'll pass on that feature.
