How to add art gameobject?

This is probably a very basic question, but it has me baffled.

I was working on a character controller, and had added a cylinder gameobject that I was controlling. Now that I’m done with the controller script, I want to add a png image as art to the cylinder so i don’t see the cylinder itself but rather the art I have.

How can I do that?

Make a plane and position it near the cylinder the way you want to see the texture. Then attach it to the cylinder(drag and drop the plane into the cylinder in the heirarchy). Put your texture(the png image) upon the plane. Now select the cylinder and in the inspector uncheck the mesh renderer option. This will make the cylinder disappear and u will see the plane with your texture upon it.
