Here is what I tried:

class Window(tk.Frame):

    def __init__(self, master = None):
        tk.Frame.__init__(self,master)
        self.master = master
        root.bind("l", self.load_image)

I get this error and it doesn't make any sense to me:

Exception in Tkinter callback
Traceback (most recent call last):
  File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 1535, in __call__
    return self.func(*args)
TypeError: load_image() takes exactly 1 argument (2 given)
