Permissions needed to "edit image"? What permissions do users need in order to access the "edit image" menu in assets?

Some users can't access this, but I can't see a specific permission for this listed under:

Settings > Users > User Groups
Maybe this is what you are looking for 


  When the deleteFilesAndFoldersInVolume permission is not set, the user cannot edit the image. And dragging files into other folders result in an error.
