How to move files to parent folder, until parent folder isn't the only file in the directory

Question

I have a bunch of pictures in a folder

C:\Users\Home\Documents\Folder1\Folder2\Folder3\Folder4

Which looks like this:

Documents:
├───Stuff
├───Music
├───Text
├───Folder1
│   └───Folder2
│        └───Folder3
│            └───Folder4
│                 └───picture1.png
│                 └───picture2.png
│                 └───picturex.png

Since Folders 1-3 have nothing but a folder in them, I'd like to delete them and move my files to:

Documents:
├───Stuff
├───Music
├───Text
├───Folder4
│   └───picture1.png
│   └───picture2.png
│   └───picturex.png

I'd like apply this to multiple folders, quickly. How could I achieve that?
