I'm attempting to add a .jpeg image to my GUI while it has several other widgets.
With my code, I can display the image in a separate Tkinter window when I use the following command:
#self.label = Label(image = self.img)
However, whenever I try to add the image to the original Tkinter window, I get the error seen below my code. The way I tried to add it to the original Tkinter window is:
#self.label = Label(frame, image = self.img)
Oddly enough, when I try to replicate the error in a shorter version of the code (such as directly below), it works. HOWEVER! To replicate the error in the shortened code, you need to create a different error first. Example: Replace text = "Try" with text = "%s" %yikes (because there is no variable yikes it will give you an error). After you change the code back to the EXACT way it was before, it produces the error I've descried below (TclError: image "pyimage__" doesn't exit). At the very bottom, I've included the entire class since I'm having difficulty consistently replicating the issue. I'm using Python 2.7 and Canopy 1.5.5.

I found the issue!!
I used askopenfilename() in the very beginning of my code, which opened an extra Tkinter window. As a result, there were two Tkinter windows open and confused the program.
By sending everything to the first Tk window that was created (and removing the second), it resolved the issue.
