How to get images to planes objects to receive shadow? I'm following this tutorial where you create a popular illusion using images as planes.

However, I can't seem to get the object to receive shadow unlike other objects I've worked with before. It could be that the nodes I've used to get this result is a mix shader that uses the images of the back and front of the illusion with backfacing but I don't know how to get around this.
After some looking around, I found the solution. Since I was using only image textures and a mix shader no shadows would be created. I had to put the images through a principled bsdf node before giving it to the mix shader so shadows could be created.
