Looking for a way to bulk edit images uploaded to Squarespace

Hello, I am trying to bulk edit the filenames of images that are uploaded to my site. I have looked through a lot of the how-to pages in Squarespace's documentation, but I haven't found a way to access all my images (without creating a new page). I find it hard to believe that there is no way in Squarespace to access my image library to bulk delete old photos or easily edit image filenames, maybe I am just looking in the wrong place? What am I missing?
