Pictures cache folder

I’ve just discovered that it was possible to cache pictures for a given media provider, so I’ve got a few questions about that:
Is it possible to chose the cache folder ? For instance to store it on external SD rather than on the phone itself
Is it automatically updated whenever a picture is updated on server side ?
Does it cache also artists pictures ?
Thanks in advance

There’s a setting for the location.

For the record images are already cached on the provider it just pre cache all. Including artists.

The images are updated if the provider returns a different one. If it says it’s the same ID or path then it’s not.

Found it, thanks for the answer!
