Need a random sidebar plugin…

I am needing a simple ad/image randomizer for my sidebar. No extra coding, no subscriptions, just something that can simply take a handful of ads or essentially images from a specified list (URL or media library), and randomly display them in the sidebar (not as a slideshow) upon page refresh. And need to have each image go to a specific page/URL upon click. Have tried a few ad widgets but become too involved. I am just looking for something that will handles the internal ads/images for a site and points the user to a page within the site. Any ideas?
