I just upgraded for the free pro upgrade and am trying to do a bulk image optimization and not sure if it's working. I keep running Google page speed test and it's the same as it was before so I think I may be doing something wrong. After logging into pro it made me download a file and i'm not even sure how to install i ton my WordPress instance (or if I need to). I know you mention there is a way to compress all images in bulk on the site but don't think I'm dong it right. Please advise.
