@marek I can see the value of this and generally like it. However, given that Friendica lends itself to larger posts than Mastodon, including posts that might use multiple images interspersed within the body of the text, I am wary of any solution that compiles all the images in a post and displays them as "attachments" at the end.

There are times when I want to use images in the middle of a post, and they'd become much less meaningful in a compiled cluster at the end of the post, even if they were in a much prettier grid.
