Image Attachments

The Image type is defined in ActivityStreams Vocabulary.

In the following, we test how various configurations of it are rendered.

A ❌ in the support table means that the entire message has failed to parse. A "-" means that the message was parsed, but no attachment was generated. The text, e.g. image or unknown is the the media type the Fediverse application determined for the attachment.

We furthermore wish to point out that having several links in the url property is useful to both offer the attachment in different formats and say dimensions, e.g. one high resolution and one low resolution one.
