I am looking for a photo gallery (preferably open source) with ephemerla sharing - eg I can create links to a photo album that can only be used once, with the (not foolproof, but enough for laypeople) JS necessary to prevent the photos from being easily saved to disk.

Does one exist already? I can get close to this by using Signal’s ephemeral messages but would prefer a solution that doesn’t require people to install apps.

(Threat model: family members and friends who might not be trusted to be privacy respecting and might reshare photos on social media)

Thanks!
