Does anyone know of a service (ideally docker image - probably with app) that can be used to securely share family pictures?
The idea is, that some relatives don’t respect wishes of not posting to social media and to prevent this we want to securely share images they can look at but not do anything else with.
Even if I send an image to my mom and she knows not to post anywhere, maybe my aunt wants to see that picture, asks my mom to send it to her and then she posts it, without us knowing.
Probably only works with an app because a browser can’t block screenshots.
Is there anything like this out there? Doesn’t have to by anything special. Just a web backend for us to upload pictures and a client (probably through a URL) that can then browse them without allowing for screenshots, sharing, downloading, etc

There is nothing you can do about users taking screenshots.
What most professional photographers do is watermark the low resolution preview pictures, and only genrate download links once paid
Actually, there is plently that can be done against screenshots (plenty apps does that). But someone who takes a photograph of the said phone viewing the picture is a different matter.
You’re basically looking for DRM and I’m not aware of any DRM system that you as a non-media-conglomerate can use.
I’m also not aware of DRM that is actually effective. It’s mostly snake oil or, at best, “please don’t steal”-signs.
The ultimate Achilles’ heel of any DRM system is the analog hole: As soon as the user has an image on their screen, they can take a photo of said screen and share that in any way they want.As with multi-media piracy, you cannot solve this issue using technology.
There was some discussion about adding DRM Management into the JPEG standard, but I don’t believe that actually got implemented.
Signal, Whatsapp, and I think even Snapchat, has view once images. But it’s best effort, somebody could certainly take a photo with another phone, or even disable the anti-screenshot feature in the option screen. It just raises the bar.
Probably not. Anything like this would probably be overrun with or specifically designed for people sending shit like CSAM.
Honestly just you asking about this makes me very suspicious of your intent.
That said, of course anything like this is also functionally impossible because a determined person could just get around any sort of measures you are imagining, either natively on the device or just by taking a picture of one device with another.
So either you clearly have not thought this through or are looking for something like this for illicit purposes.
Either way this entire post is
You seem to be a very judging person. I just hope you’re not projecting your own thoughts onto other people.
I have thought this through, and obviously there’s always ways around. But I know that my relatives are not tech savy enough, and taking a picture from another phone isn’t something i can control anyway.
But why am I explaining this to you? The only thing on your mind seems to be CSAM, which is very suspicous and weird.
