I have a site with a pretty large media library. The images are mostly in JPG format. When I ran the site through Google's PageSpeed, it heavily penalized the score because the images were not optimized. I've tried a few plugins like Smush, but the PageSpeed still says the images need to be optimized. Which plugin or solution can optimize those images enough improve the score?
