It used to be CC0 on Unsplash but some time ago they moved from that to a custom license with some special restrictons, which makes it impossible to use in other Creative Commons work: https://unsplash.com/license This also happened to a lot of other similar photo sites unfortunately.

Preferred for the feed would be RSS I’d say, but maybe Twitter is good on top for promo.

Thank you!
