Via Tender: Proposed guidelines for image uploads

Assigned to Tender discussion #348. As reported in Tender:

1. Only allowed resolutions are 1920x1080 and 1280x720.
2. Images should not be resized to get to the correct resolution. If they are too big they should be cropped,if they are too small they either shouldn't be used or should be used to make composites.
3. Do not include extra text on the images.
4. Do not include borders in the images, or take a poster and just add a solid background to it to make it into a fanart. Your image should take up the full image space.
5. Don't upload a 720 image if a 1080 version of that image already exsists. If a 720 version exsists and you upload a 1080 version of the same image please ask a mod to delete 720 version via "report the problem" button.
6. Each backdrop should be unique. Please don't upload the same fanart many times with minor differences such as slightly diffrent zoom, angles, posses, diffrent colour letters or a minor extra image pasted over top, etc...
7. Make sure you are uploading the image to the correct movie. Some movies do have duplicate or similar names and mistakes do happen so double check before you upload.
