It sounds so simple, but I can't seem to find a plug-in that will help me do this. Just need to have the image on the front page (it's a static page, not a post) change with each new page view/reload. (I tried NextGen Gallery and JS Banner Rotator, but it didn't seem that either includes this function.)
If there's no plug in that will do this, is there another fairly simple way to do it? Could I do it with css?
