TincyMCE image delete to server with Laravel

My question is the image is uploaded and saved in the folder in the server side in the given path but if a user uploads 5 images and deletes 4 images then I should delete 4 images from the folder in the given path.

So if any user will press backspace key and delete key then delete should be done from whatever folder it is saved then please let me know or share me the code.
