Introduction

Local storages and traffic are expensive, especially in cloud envionment.

There're many cheap and large cloud/remote storages services,
most of them provide cheap and fast HTTP access.

ex. Amazon S3, FTP+HTTP Static Image Hosting Services...

pictor is designed for these environment.

pictor basically works as following:

  • upload is accomplished by pictor. cloud/remote storage can do if possible.
  • convert is accomplished by pictor.
  • download is accomlished by cloud/remote storage. pictor can do if you want.
  • all files are stored in cloud/remote storage. local storage can do if you want.
  • all variant files(generated by pictor) could be deleted at any anytime. pictor will generate it on demand.
