Photo Hack Day 4 erupts April 6th, and runs nonstop through the weekend. The first Photo hack Day brought together photographers, web designers, photo editors, and computer scientists for the first image-centric hackathon. Since the original 200 hackers threw together almost fifty mashups in a single weekend (two years ago), Photo Hack Day has blossomed in number, creativity, and excitement as it readies itself for a fourth rendition. Lead sponsors Aviary and Facebook look forward to "[a]nother full weekend of photo centric awesomeness."
This week we’re spotlighting the Flickr API, one of our most consistently popular APIs. Flickr is the fourth most used API in our directory appearing in over 600 mashups. Each of the mashups below leverage Flickr and have been named mashup of the day since August.
Of all the hundreds of tags you can see in our mashup tag cloud, the second most popular behind "mapping" is "photo". How popular? As of now there are over 200 photo-related mashups listed at ProgammableWeb -- 202 by today's count.
