It is not a legal episode, because the episode is not aired yet. You can't add a pic from an episode which is not aired yet. Then, you're pic is definitely not named correctly. If it was the case, it would have been something like: 401****.png/jpg
You did not renamed, you just reuploaded the same pics. The name is still wrong: it must be 401 and not 4x01. Then, even if it was aire only on abc.com, the episode is not aired yet. so until sunday after the ep, we can't use these pics. Last thing, we can see the bottom of ABC logo on your pics, which is not allowed :)
Why can't I change Anna and Kristoff's physical description like Anna having Blue eyes and Strawberry Blonde hair, It is what Elizabeth Lail has. while Scott Michael Foster has Dirty Blonde, and I think he wore brown contacts in his first promo video.
