Bluesky is getting its own photo-sharing app, Flashes

To make this work, Flashes simply filters Bluesky’s existing timeline for posts with photos and video posts. (In the future, Vogelsang also plans to add metadata to Flashes’ posts so Bluesky users would have a way to keep their feeds on Bluesky’s main app from being flooded with photo posts if that became a problem.)

It seems an odd thing - I'd think just filtering out text posts would be a filter you could have on a standard app, now you need two apps to see the content in the same feed.
