On Google PageSpeed Insights I am getting warnings that some of the images on my site are uncompressed (or only slightly compressed). I would like to be able to find these images and use a higher level of compression on them. Unfortunately, I cannot find an easy way to locate them. Here is an example of the type of message I get from Google:
