identifying large jpegs

Hello, I have a grade C for compress images and am trying to work out which ones are the offending images - I don’t know how to interpret the results to identify them - please can someone enlighten me?
Many thanks.

If you click on the grade it should take you to a list of the images that caused the issue.

Many thanks. Got an F for Cache static content, is this something I should address?

Probably, particularly if you expect people to load more than one page on your site or come back again.
