The separate forum is a good idea, so I've just created a new section called "Encyclopedia" where you can report all the mistakes you find.
In the case of picture problems, it's even simpler since I accept picture contributions:

(I prefer theatrical posters of the movie, when possible...)
P.S: do not worry about "Santa Clause", I will replace the picture myself.
