Please put photo of actor from movie not the current photo. Showing current photo is confusing when I look up old movies

This would be very useful. However, it is impractical.

IMDb only uses image that it owns, has permission to use or licenses. Most older films have few, if any images available. For example, The Thin Man
(1934) 

(http://www.imdb.com/title/tt0025878/) only has six images available in the photo gallery (http://www.imdb.com/title/tt0025878/mediaindex). Even with the number one film in IMDb's Top 250, The Shawshank Redemption
(1994) (http://www.imdb.com/title/tt0111161/), the photo gallery (http://www.imdb.com/title/tt0111161/mediaindex) does not have the suitable images necessary to implement your idea.
