Good question. It was set as the default image, but with that default removed it still seems to be top voted. But what image to set as default? I would prefer this one perhaps. But maybe another moderator can decide. For older movies, we are not always going by the "title only" look as the first choice.

If we're going to set a default for Star Wars, I think this one would be good.

That works fine for me. Feel free to set it!

Alright, I set that one as the default.

I looked into it and cross referenced the Year (1977) with other Star Wars movies, yet this shows: http://www.imdb.com/title/tt0076759/ So is the Year possibly wrong here too which is why people have been adding that poster?

EDIT:
Seems like the official Title is "Star Wars – A New Hope" as in the official movie list on Wikipedia it seems to go in this order:
IV, V, VI -> I, II, III -> VII, VIII
(Original Trilogy) -> (Prequel Trilogy) -> (Sequel Trilogy)

So I guess its right after all?
I guess the only thing technically that needs changing is the name to officially Star Wars: Episode IV - A New Hope like on IMDB?

The original title is Star Wars, even the Wikipedia page states that, and we do not add a translated title to a language page that matches the original (no En on En translation), so A New Hope is correctly added as an alternative title. Nothing to change here.
