ok - i have been looking at ways to optimize the site http://www.handyguyspodcast.com
When i run the page speed analyzer add-in for firebug and review recomendations it lists several images that I use as buttons as not cached. These images don't rarely change.
The buttons are simple html within my sidebar that i use to allow for users to subscribe.
How do I force them to always be served from cache? Is this a dumb question? If so, sorry.
