Answer:
For an image to be reflected back the whole wavefront must back scatter elastically, keeping its direction and phases. This is where the "flatness" discussed by others comes in.
On a rough surface part of the light may scatter elastically, but it becomes a point source at each bump, losing the phase of the wavefront, i.e. coherence. An addition of millions of such point sources is the result, the loss of coherence and image information; the color is a matter of what wavelenghts the wall has absorbed.
As others have stated the wavelength of the light defines how flat the surface has to be.

Answer:
More light is reflected off a mirror and it's specular reflection its all being reflected in the same way . You get diffused reflection of a wall instead because the rough surface , and has a result light rays don't converge like they do in mirror, so you don't see image form on the wall
Hope it's helps you dude☺❤
