Reader Question: Alternative to Flickr and Picnik?

So it’s not bad enough that my beloved Picnik is changing life as I know it by ceasing to exist next month. {Bad Google!!!} but I was looking for an image for a post yesterday and to my frustration, Flickr had the hiccups and I was suddenly at a loss.

So tell me, what is your favorite source for post photos? {and if you have an easy-to use replacement for Picnik, I’d love it if you’d share that too!}
