OK. I have been through ALL my covert art, downloaded my preferred ones (which for films is the original poster from it's theatrical release), resized them all to the same dimensions and resolution, and then, again for films, removed the release date, 'Coming Soon', etc. wording from them. For music artwork, I have removed the 'Contains explicit....' wording for those that didn't have 'clean' versions.
Obviously as I add to my library the same customizations will be made.
So how can I now submit all my covert art to the relevant DBs so that should my house burn down I do not lose it all. And you never know others might want it the same but couldn't be arsed to do it themselves (not that that's a bad thing - I have OCD so things must be identical, hence the dimensions/resolutions being the same).
PS: Feature request: When doing right click > Get Movie and TV info, can you set the default to have the 'Use image' checkbox unchecked.
