Chrome displaying low-quality images

Hi, guys. So I just this week noticed that Chrome is displaying a much lower-quality version of my images on my website. If you take, for example, http://theroomsproject.org/andrew-k, and look at it side by side in Chrome and Safari, the difference in image quality is tremendous. I’ve checked all of my plugins, and none of the plugins seem to be affecting the image quality. It’s a photo project, so image quality is essential. Any thoughts as to why this might be happening?
