App for allowing you to host some huge ass photos on the web.

This is basically the code for the site: HUGEpic which I maintain.

• The Garden of Earthly Delights - 222Mb
• Lord of the Rings mosaic - 11.7Mb

The code consists of the following major pieces:

• all server-side code is Tornado
• there are two databases:
  • MongoDB main storage
  • Redis primarily for caching
• connecting Tornado and MongoDB is Motor
• all message queue processes handled by RQ
• the client-side browsing is all thanks to Leaflet
  • with the annotation drawing thanks to Leaflet.Draw
• Amazon S3 and CloudFront keeps all the images except for temporary copies

More has been written about the technical here.
