Dynamic content of Footer Widget

I have a webpage with some premium theme. This theme has footer designed with Footer Widgets. I have four of them and can create four columns in footer this way.
Is there any way to dynamicaly (for some pages YES, for the resn NO) change fontent of ONE of those footer widgets?
I would need some text and Formintaor shortcode on most pages, but only an image on some specific pages.
Any idea?
