▶ Suggestion I first noticed how Bluesky was handling thumbnails months ago when starting the Repeal OBBBA effort. I monkeyed with images used in admin/site_settings/category/branding but no joy. Other sites: X, Facebook, Reddit, Discord, mastodon all generated the thumbnail just fine so eventually I…

[이미지] philh: I am hoping folks can help me sort what image needs to be added to Discourse to get very cool thumbnails on Bluesky. The OpenGraph image setting should do it, here’s how ours is configured for Meta, to reflect what you’re seeing in posts [image]

Thanks @awesomerobot What size and type is your OpenGraph image? I am trying different sizes but no change so far. Results so far: @phillipnhenry.bsky.social on Bluesky

It’s a 2400 × 1260 JPEG, which is double the 1200x630 recommend (helps cover devices with 2x pixel density). I believe most social networks will cache open graph images, so changes may not appear immediately.

I changed to something larger that I had handy (a favorite). tried on two sites and the change with Bluesky post thumbnails was immediate so no apparent caching. OpenGraph image → 1500x500 jpeg [soaringtwitter] Thanks again @awesomerobot marking as solved.
