I want to upload new images for this movie http://www.imcdb.org/movie_338844-Cazador-de-asesinos.html
with screenshots that are slightly sharper and don't have the tv-channel watermark. How should I do it... upload to imageshack and add a comment for each vehicle? Or is there a better way? Can a movie be "unvalidated" so I can go through and set the pictures, then revalidated? (i'm not ready yet, just asking in advance )

The easiest way is probably just to upload the images to imageshack and post them here on the forums under the movie's title.

That's a good idea. Thanks!
