Hi jordanenendchannel !
I see you've been uploading and replacing a lot of show posters with what looks like posters from tvdb.
You should know that they resize their images and they are a lot smaller in size than what we'd like.
With that in mind other sources are preferred and please always make sure that you have the largest version available before uploading a poster.
Please get back to me when you've read this :)
Aidan
