There's nothing inherently wrong with images - but if a website shows more of highly upvoted content; and if users can upvote a cute cat picture after 10 seconds while a written article takes 10 minutes to read, the cute cats are going to dominate.
That doesn't really help much. Most enthusiast subreddits are full of posts that are just "look at my [basic standard hobby gear] picture". Even those places are overrun with this.
Is looking at images profane all of a sudden?
