This is Gander
We posted a while back about Squetch! from the minds at Elepath. Last week we came across another creation of theirs called Gander, which is just as easy to use with simpler interactions. Gander essentially creates a photo collection bucket with a URL you can share. Anyone you share this URL with can upload their own images. With restrictions, permissions, and options removed, the experience is uber-minimalist. We love it and hope you find it useful as well.
