[schmarty] as long as referer headers still work, i'm imagining you'd pull it out of your server logs on the media server. webmention `target` is whatever file is being `GET`, `source` is whatever is in the `referer` header. from there, process it like a webmention _but_ in addition to accepting links to the media, also look in `img[src]` and the dozen or more other ways that media can be loaded in HTML lol.
