Is there an add-on (or any other way) that will allow me to edit the file names of images in the file manager after they have been uploaded? Not the Title- that can be edited under "properties" in the drop down menu. I have seen other forum discussions about this and people suggested downloading all of the image files, renaming them, and then replacing each photo in the file manager with the correctly labeled file. I felt completely daunted by that task but began doing it only to realize that when I replaced the file, it left the file name of the original image file.

I am a novice and, though I can figure out a few things through the magic of the internet, I do not personally know anything about coding, so any help is appreciated, but also anything very complicated might be over my head.
