Images Guidelines question: What to avoid

I was looking at the FAQ section for Photo guidelines. There doesn't seem to be anything listed regarding the following issues. (Not sure how you can retrain contributors who don't look at the guidelines. (maybe a one time only email to all contributors like you do for the "year in review to contributors email" that you put out thanking us for our help. You obviously have out contact info. Do you have contact info for major event photographers, syndication agencies and studio contacts?)

First: contributors who get images from screencap sites need to know that those sites generate dark images. They need to brighten the images to match how they really should look. Without doing so you tend to get a gallery of dark muddy images. Also size matters.

DVD menu pages: Someone with access to French language DVDs has been uploading menu pages. This seems unnecessary. Sometimes you can't even tell what the film is. 


DVD back page: This seems unnecessary. Sometimes you can't even tell what the film is. The quality of these tend to be not good.


DVD multi-pack ads: This seems unnecessary. 


Actor selfies with co-stars: Usually background or kid actors trying to fill out their galleries. However these tend to clutter up the movie gallery. Maybe avoid tagging the film so it's just in their gallery? This tends to happen at the premiere events also.


Sequencing redundant images: Why tell a story in four images when you already told it with one image?


Behind the scenes images that tell you nothing about the film. Usually no actors or directors etc.  Can you even tell this is for the new Terminator film? 

Event photos that are redundant or duplicates: Event photographers need to edit themselves. This is an extreme example. Marvel films tend to put up an excessive amount tof very similar but not duplicate event photos. Also whoever uploads event photos (either the photographer or the studio) needs to make sure they are not uploading duplicates. There are a TON of event duplicates.


Letterbox images: Images that already have the black bars when uploaded tend to make for a crappy looking gallery. The system already formats full frame images with the black bars so these are now double letterboxed.
