Custom images for projects

[jzakotnik]

Quite often there is the request to have custom images in the project. For example in Tunesia the project is about a kindergarden, so a photo of the kindergarden would be nice.

There might be two options:

• Storing it as project data in the blockchain, maybe base64 encoded in one of the custom fields? Could also be very low resolution
• Storing it on the document store, but this seems somehow more unstable
