Image Block

If an image block is overwritten with another block, the block cannot be interacted with, no matter what block it is,
It will be a useless block. It would be nice if it was a creative-only block. Then I would like to make an image block. The design would be like an X drawn on the surface of a stone. The idea was taken from MinedApple, a Minecraft YouTuber in Korea. He said he saw this block in his dream. I hope his wish comes true. As always, thank you Minecraft!
