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.
