Insert different images in sidebar on different pages

I am looking for a plugin that allows me to insert images into a sidebar only on certain pages that I select. For example: I want the ability to insert 1 image into a sidebar on 1 page and then insert a different image into the sidebar on another page with the result that the two pages have 2 different images in the sidebar. I want to control the pages and the images that will appear in that page’s sidebar.
