The voting system is in a sense at fault. Examine the algorithm: . In the time you can read a reasonably long article worthy of an upvote, you could rate at least 25 images. Because of the nature of the time fall off inherent to the algorithm, human's natural inclination to keep hitting the dopamine button and that you can only give one upvote rather than rate content out of 10 or 100, pictures will always dominate over words as content.
