This is a node group made by blender, you can use it to quickly load multiple images on one material at once. Especially some repetitive materials, such as playing cards, books, leaves, newspapers, windows, photo walls, particle etc. In general, you may have to create many different materials, but with Easy Textures, you will be very fast to complete these just by only one material. Even make the images random or orderly on your objects. Of course, it can be used in Cycles and EEVEE, or with Array modifier and Geometry Nodes.
