There are a few indications for the main images in the infobox. For example:
 * High-quality is preferred over low-quality
 * Latest appearance is preferred over former appearance
 * Screenshot is preferred over concept art
 * Official image is preferred over behind the scenes image

Therefore, the screenshot is preferred unless its quality is so low that it's needed to add a concept art
