@heluecht Ah you mean picking size 0, 1, or 2 if we provide resource-id instead of ID? That would be solved by returning the IDs of the images when we query it from the Friendica side. It would then not require any special logic in the Mastodon API or even changes there. We just need to decide if we break the current Friendica API format by introducing it directly in the link array, produce a second field of IDs, or a second field of "scales" or something which itself is a collection of maps with IDs and links.
