Is there any way to upload images on behalf of the GM?

Hi, I was wondering if there's a way to automatically upload a bunch of tokens or other images for the GM. Obviously you'd need some sort of authentication here (so you can't just add files to someone's library without their permission) but it seems like it could save a lot of time if it were done right. But it looks like this just isn't possible with the API, or am I missing something? Thanks!

Images are stored on a per-account basis, you cannot upload something into someone else's account.  However, if your goal is to have a shared game where two GMs are uploading things, yes you can do that. But each person's images are theirs. If they delete it it will be deleted for everyone (although there may be a delayed reaction due to how caching works).

And to be clear, Mod Scripts have no access to uploading files.
