What could I do to improve the hit rates?
Some of those are responses to IMS requests. Which your rule forces reload requests to become.
Maybe the server is simply responding with 200 OKAY regardless of getting an IMS request.
Maybe the requests actually did have ? query strings. You placed your cactch-all dynamic content rules for preventing storage of badly controlled dynamic pages above the image caching rules.
Maybe several of your users favor Chrome. I've heard that browser sends no-cache header by default. Which results in middle proxies being unable to cache anything for improved access, and in fact degrade access for other browers.
