A server config option so that only ops may upload images would be appreciated.

A separate "op only" visibility option, so that some paintings uploaded by ops can only be viewed in the selection menu by other server ops. (Similar to the "hidden" option, but "op only," and designated to its own menu tab that only server operators can see.)

Asking on behalf of a server owner who may add the mod to the pack for their server if these config options are added and functional.

(I already use it on my SMP and like it, the other server owner has a bit of a different vibe going though and only wants to add Immersive Paintings if they can prevent players from uploading inappropriate images or abusing images used for dungeons.)

(We figured it'd make sense for there to be an "op only" permission so that ops can upload "approved" images for server-wide use, as well as an op-only selection tab so that builders working on the server will be able to share paintings for dungeons without random players being able to re-use those paintings to cheat around puzzles.)
