Another thing, #Mastodon can't see more than 4 images in a post. I have made this issue, hoping on it getting fixed. https://github.com/mastodon/mastodon/issues/19454

@freeplay If you set 4 acceptances, you will get a link like this when you exceed it.
This link will take you directly to the public post on the remote server. (So it won't work because it can't be seen on followers-only posts)
I think that the limitation in Mastodon is because we want to reduce the number of cases we accept, so we need to consider some kind of workaround at the same time. This is one of them.
