What Imgur alternatives do people use when Imgur is down

The only image service that I've been able to successfully use for posting my images on The Verge has been Imgur. Well Imgur has been down almost constantly the past few days, so I wondered what other services do people use to share their images on The Verge? So far I've gotten blue boxes using the full image link from Flickr, pic.twitter, Picassa, and Imageshack. What service should I be using?
