A thick plane mirror consists of two surfaces, (top and bottom) where the reflection can take place.

The images are formed after reflection from both the surfaces, except for the first image. The second image is the brightest of all as minimum absorption takes place and it bounces of the silvery layers which makes the bottom surface.

All successive images are formed due to multiple reflections and absorption and thus they are not as bright.
