Yes, 360° images are possible here (example).
It works with kuula.co 360° out of the box, using either their Embedly or HTML Embed sharing options. The HTML embed (iframe based) sharing option is preferable as it shows up larger.
If you want to use a different service for sharing 360° images, and similarly for any service for sharing virtual tours: it should work with Embedly / OneBox embed compatible links by just posting them on their own line here in a Discourse post. Again for the kuula.co example, you would write:
https://kuula.co/post/7lMbd
Again, results will be better when using iframe code snippets to do the embedding. To make that possible, tell me which service you want to use as I’ll have to whitelist its domain in the admin settings first to make embedding possible.
