TKinter python 3.x resizing an image – Photoshop

I would like to resize an image using TKinter.
Please note that I will not be using PIL for this.

How can I currently have this image, which works fine.

logo = PhotoImage(file="logo_dribbble-01_1x.PNG")
label = Label(f1,image=logo, borderwidth=0, highlightthickness=0)
label.pack()

logo_dribbble-01_1x.PNG

I would like to resize this image so that the logo looks smaller.

I tried doing this, which was suggested here

smallLogo = PhotoImage(file="logo_dribbble-01_1x.PNG")
smallLogo = smallLogo.subsample(2, 2)
smallLabel = Label(f1,image=smallLogo, borderwidth=0, highlightthickness=0)
smallLabel.pack()

But this creates an empty label without displaying the image.

I tried to resize the image using Photoshop and use that image and then use that .png image to display the smaller image like so:

logo = PhotoImage(file="logo_dribbble-01_1xsmall.PNG")
smallLabel = Label(f1,image=smallLogo, borderwidth=0, highlightthickness=0)
smallLabel.pack()

logo_dribbble-01_1xsmall.PNG

But, I get this error when I try to run the code
_tkinter.TclError: encountered an unsupported criticial chunk type "mkBF"

How can I resolve this issue?

    I had to keep a reference of the image that was being used by the label like so: 

    logo = PhotoImage(file="image.png")
logo = logo.subsample(2, 2)
label = Label(root,image=logo, borderwidth=0, highlightthickness=0)
label.image = logo
label.pack()

    The following code worked for me:

    from tkinter import *

f1 = Tk()
smallLogo = PhotoImage(file="image.PNG")
smallLogo = smallLogo.subsample(2, 2)
smallLabel = Label(f1,image=smallLogo, borderwidth=0, highlightthickness=0)
smallLabel.pack()
f1.mainloop()

    Note I’m on tk-8.6

    smallLogo = PhotoImage(file="logo_dribbble-01_1x.PNG")
smallLogo_one = smallLogo.subsample(2, 2)
smallLabel = Label(f1,image=smallLogo_one, borderwidth=0, highlightthickness=0)
smallLabel.pack()

    I think this will solve the problem for you.Your variable for PhotoImage is the same as variable for the Subsample to trim the image for you.
    I change the variable for subsample to smallLogo_one the parsed it to the image attribute in the Lable.
