ActivityPub C2S: How to upload images?
ActivityPub Client to Server part of spec doesn't have any description of this, so we could implement uploading an image as a separate step before posting the image object ActivityPub way?!
How should I do this in Pleroma implementation? Solving this problem is the last step of Basic implementation of ActivityPub C2S in AndStatus: https://github.com/andstatus/andstatus/issues/499
If you don't know / cannot decide how to implement this correctly in the "ActivityPub way", I could help here.
