ID has no picture

[Namenox]

It makes no sense to have a digital ID without a picture. I know its just a demo, but the problem is I can not find anywhere a specification of how to deal with images and credentials (storage and transfer)

Im developing a use case in which the user gets his ID from the goverment, like in the demo.
At the entrance of some event, I want to present my digital ID. However, I could have given my mobile phone to a friend, so it is necesary that the image is somehow on the credential.

Supposing I would use IPFS for the storage of the picture (which would make it public and therefor affect my privacy), in the credential I now have a field like this:

avatar : Qmsakjdhfa8haisgha9gh0asfiajsd...

But, how would the verifier access this picture? As far as I understand, it is on my phone, and I would need to be running an IPFS daemon in order to make it accesible for him.

Thanks
