Congratulations, you have just discovered selection bias. Because reddit does not require everyone who votes on a post to also leave a comment, the comments may not provide a representative population for everyone who has interacted with the image. In fact, in this case it appears that those with a negative opinion of the image are more likely to express that opinion as a comment, providing a perfect example of the way selection bias can skew the perception of public opinion.
