On a multisite, I have an Editor role that is assigned to subsite1. When that user logs in to their assigned sub-site (that user is an 'editor' on that subsite) and goes to the Media page, they see the media for their site.
But that user cannot click on a picture (media item) and get to the Edit screen (as when they need to rotate an image, for example). That capability appears to be a function that only works for the Admin and SuperAdmin role.
I've looked that the Roles and Capabilities page in the Codex (here https://codex.wordpress.org/Roles_and_Capabilities ), and don't see how to add that Media Edit capability - I don't see a 'Media Edit' capability.
How can I let the 'Editor' role Edit Media?
Edited to clarify that the user (with the Editor role) is logging into their subsite, and can see the Media page, but cannot click on a media item (picture) to get to that picture-edit page.
