Hey guys/gals!

Got a caching question for you. Is there a way that I can cache a dynamic image on the client side so that it isn't reloaded every time that they visit a particular page? The image that is....

For example...



I would like to set a time limit that this image is cached, say 6 hours. Right now its being reloaded every time that the page is refreshed. Im trying to figure out a way that will cut the amount of bandwidth that is being used.
