Tkinter PhotoImage Question

[Adonis]

I have two classes one class inherits dict(), this class just takes in a 
path argument much like glob.glob() and loads the image using PhotoImage 
into itself, no biggie works fine. The other class inherits Frame and it 
implements an add(self, **kw) method passes all of its arguments to a 
Button. My question is that when I load the images with the first class 
and then use dict.get(name) as the image argument for the add method the 
image does not show up, mind you the variable holding the dict is seen 
by the whole class so its not a garbage collection issue, but if I put a 
command in the argument list it works just fine?

Any help is greatly appreciated.
