Why not use any GUI photo gallery? Specific format databases are often not enough flexible. Most solutions are bloated and packed with too many features. File permissions User read-only flags are set automatically, however few programs respect them. You may still be able to remove files via GUI and python. If you are not aware of superuser privileges, you can set the data directory protected from even root: `chattr +a images` This will however only protect directories where the images are, but does not apply to files itself. RAW photos It is possible to manually add raw files so it will get all the management features. temporary broken; I do not recommend raw file formats, as they are suspected to poor support in the future, require long toolchains and complicate metadata management. Image is not valid My cheapest camera produces images which result an error in attempt to display in terminal. That's a chafa library or perhaps camera issue. Use non-interactive upload. I don't know exactly the source of issue. Any kind of AI is beyond the scope?
