I've recently gotten a camera after not having taken a single photo for more than a decade. Until now, I've stored the photos I've had (taken by others) in a Picasa web album. I want to remove them from Picasa, partially because I'm trying to limit the amount of personal content that I leave on the web. On the other hand, the good thing about having it there was that I didn't need to worry about the photos disappearing if my computer would crash and so on. So, now I'm trying to figure out the best way of organising my photos offline but with adequate back up. Is an iPhoto album (backed up on an external hard drive) sufficient? I just want to store them properly (as opposed to edit).
