Hello, I'm working to optimize and clean-up a website that I was recently asked to assist with. The first thing I did was install WP Smush and run it on the images contained within the site. Unfortunately, both the Hummingbird performance report and Google Page Speed Test show that I have a number of large images that have not been properly optimized. Please help.
Additionally, I'm having trouble enabling browser caching and gzip compression. I checked, and my hosting company (Rackspace Cloud Sites) says that all is enabled on their end.
