# Image storage

Image **Storage**

* should peers that belong to the decentralized image store be required to store data on IPFS?
  * to take advantage of content addressing
  * to allow for replication of data accross IPFS nodes?

* IPFS backend for image storage should be prioritized

* crawler subsystem should be migrated to the Image storage abstraction layer as soon as possible.

* flow->backend(s3/ipfs/etc.) mapping should not be staticly defined (as currently it is via YAML config file), and instead it should be dynamically settable by node operators/users
  * possibly operators should be able to enable this for users on node-startup (if for example they want to force users to only use s3 storage, or IPFS, etc.)

image storage:

* this represents storage of image that is expected to be durrable in some way
* does not include temporary storage of images on the local FS (workspace)
