thumbnailer

Generates on-demand thumbnails of images from the zoo owned Azure blob storage and (currently) specific S3 buckets. These buckets are allowed:

1. panoptesuploads (Azure storage account, public container)
2. All other paths will be proxied to Azure zooniversestatic storage account in the $web container (e.g. www.sciencegossip.org, www.galaxyzoo.org)
   • https://thumbnails.zooniverse.org/100x100/www.sciencegossip.org/subjects/thumb/54f43a24efc50104c30007d9.jpg
   • https://thumbnails.zooniverse.org/100x100/www.galaxyzoo.org/subjects/thumbnail/56f3dff05925d90043004e21.jpeg

E.g. the following URL
