Needing Tech Advice

Like most genealogists (and well, everyone) these days, I find myself with a large number of digital photographs.  I get overwhelmed when I look at all the options for backing up photographs online.  I thought you, my blogger friends, would be able to help me.

Currently I use Picasa to edit and organize them.  Most are saved on my computer that I back up on discs. I confess. I do not do this as often as I should. (Please tell my I am not the only one!) I have begun putting them in Picasa web albums where I control the privacy settings.

Is there a better way to back them up?
