So this code is activated on button press and that part definitely works due to print updated..., however the picture doesn't change like it should, even if i comment out the resizing stuff....
the programming opens a window with an image on and a button, on button click in theory the image should change

Change pic is definitely being called as when it is called it prints "updated" which it does after every button press :) wpercent and hsize are correct too and the images are definitely name correctly and in the same folder as my program :) @BryanOakley
