Is there any (preferably free) site/service out there that allows photo uploads to a single album by several people without registration?
What I have in mind is
I create a group photo album on the given site
Site provides me with an upload code
Anyone knowing the code can upload multiple images to the album, without registering on the site
The key is "without registration". There are a lot of sites that offer group photo sharing, but all that I've seen require registration from uploaders. I'd like to skip that step.
