I have pictures posted on http://www.flickr.com/photos/rcstanley
I've decided I like flickr. I can upload pictures for free. I can mark pictures as public, private, or visible to friends and family. I like this option because I can post pictures of my children and only friends or family can see them. (If you fall into one of these categories, e-mail me you flicker id and I'll add you so you can see the photos.) I can subscribe to RSS feeds of people whose pictures you like. This means I can be notified when there are new pictures instead of having to check.
My husband and I are deciding if we want to get a pay account ($25 a year). That would allow us to post full resolution pictures and have a higher bandwidth quota.
