Answer 1

The problem is that your filename isn't being treated as the filename of the image. The first non-keyword argument is used as the internal name of the image.

You must specify the file keyword argument for it to use the file as the image:

img=PhotoImage(file="mat.png")

Also, depending on what version you have installed, tkinter may not support png files. If your system does not, with the above change you'll get at error like TclError: couldn't recognize image data. If that is the case, you'll need to convert your image to GIF.
