Photos are more fun when they are shared. Thankfully, online photo sharing services make it easy to back-up your photos and share them with the world.
I use Flickr for the sharing aspect and JungleDisk for backups, plus I have an external hard drive that I backup to sporadically.
I loathe how much people email photos back and forth. It’d be a better world if everyone was on a photo sharing service. 🙂
Disclaimer: I have no affiliation to Flickr or JungleDisk. They’re just services that rock.
