Online photo sharing is getting easier every day, and many services offer an amazing number of options for free. You can batch upload your old family photos, restrict access to designated family members or make them available to the world, create fun family albums or slideshows, and even add voice or video. Digital photo sharing services are especially useful for sharing old family photos with your far-flung relatives - instead of you having to print and mail copies, they can download or order prints of their own. From the dozens of such services available online, I've chosen five of my favorite online photo sharing sites.
