Open Source Photo Community App: Photographer.io
Photographer.io is a fresh “photo community” web application (that is in beta status) for presenting + sharing photos and getting feedback.
It is built with Ruby on Rails, CoffeeScript, SASS and PostgreSQL + Redis for storing the data.
The system has a powerful “photo exploring” feature where you can find photos by category, latest uploaded, random, recommended or via searching for keywords.
Each user has a profile page where his/her photos are listed and each photo can be recommended or commented on too.
And, the EXIF data of photos are available, if a location is included, it is displayed in a map as well.
