As someone mentioned in a comment you can't put images in a Listbox, but as I mentioned in another, you could use a Text widget instead because you can put images into them. Below is a relatively simple demonstration of how something like that can be done. Its two buttons illustrate how it can display just text or a combination of the two simultaneously. Text widget are actually very versatile.
Anyway, since presumably you want a scrollable list, the Text subclass named tkinter.scrolledtext is used instead of plain one to save work. Since it's a subclass, it can do anything its baseclass can do.
