Why is this picture considered invalid???

www.listal.com/viewimage/2336766

I got the notification that it's been "deleted for this reason: invalid"
Why? It works perfectly and it's an official poster of the trilogy.

don't know, myself...I had a picture I posted of a woman's mid-section, it was also deemed invalid yet there are tons of pictures like that on the site... I'm not able to see the picture of yours that was deleted

I assume, the person who reported it and the mod who deleted it believes it was a fake.

The link is for moderators. I also think it was deleted for mistake, and I'd upload it again if it hadn't 23 votes and was added to 5 lists.
Is it possible to fix this problem, please?

From searching on google it looks like it is a fan made poster, I may try and undelete but not attached to the movie.

I may be wrong, but this might be for all the trilogy marathons hosted by movie theaters across the US (and possibly in other English-speaking countries). I saw something like this at my local cinema, which had such an event. Not necessarily official - but including posters used in theaters that aren't apart of the official advertising is something we might have a dialogue about.
