Changing a studio partner primary image on a title & a mismatch between posters

https://www.imdb.com/title/tt0430327/

The current primary image for Madagascar: The Game is low res and not widely used. The title already has this poster uploaded to it's photo collection: https://www.imdb.com/title/tt0430327/mediaviewer/rm206896129/

It is more widely recognized and of higher resolution than the default lousy looking DVD cover. Is it possible to change it to this one?

Some weird mismatches I'm curious about:

On Battlefield Bad Company 2 title, https://www.imdb.com/title/tt1625541/, this image is shown in results and title page as primary image: https://www.imdb.com/title/tt1625541/mediaviewer/rm4058309632/ 

When I try to change it to the more crispier and better looking poster already on there (https://www.imdb.com/title/tt1625541/mediaviewer/rm1991369217/), it is said that this is already set as the primary image. Please look into this as well.

The same with Half Life Opposing Force: https://www.imdb.com/title/tt0363260/mediaviewer/rm1421220352/?ref_=tt_ov_i is shown as primary poster. When this one is better (https://www.imdb.com/title/tt0363260/mediaviewer/rm1407807745/), but is already technically shown to be the primary image.

With Half Life Blue Shift: https://www.imdb.com/title/tt0363259/mediaviewer/rm2813729280/?ref_=tt_ov_i is the default showing one, but https://www.imdb.com/title/tt0363259/mediaviewer/rm361177857/ is better but can't be changed to primary because it is already shown to be the primary poster.

With Terminator Salvation, it's this https://www.imdb.com/title/tt1330058/mediaviewer/rm3594119680/?ref_=tt_ov_i instead of this https://www.imdb.com/title/tt1330058/mediaviewer/rm3388905730/ which I personally uploaded and got approved by IMDb so maybe it'll get updated in time on search results.

Why all these mismatches, am I missing something? I hope you'll look into these issues.
