Display Selected Image from Directory and Resize it - EchoLi - Oct-02-2019

Hi, I am working on a Tkinter GUI now. I would like to select an image from the directory and resize it. Now I am having trouble displaying it, even though I get the directory dialog and it is clickable.
I also want to resize the image I select, but do not really know how to put the code into the frame.

I am totally new to Python, there might be some stupid mistakes.
Thank you.
