See for reference: Fediverse, ActivityPub and the Ethics
This is how it shows up in my mastodon timeline:
There are three things going awry here to take into consideration:
- The image is displayed twice in the toot, somehow.
- Both images do not have the alt-text that was typed by me.
- The alt-text used instead is the original filename of the uploaded image.
- Regardless of alt-text. Showing original filename in the UI different to how other fedi apps use a newly generated name, and breaks expectations people may have in naming image uploads.
