How do i get rid of' Tkinter.Tcl error- could not recognize data in image file'?

Every time, even though I have the source file, the same error message appears - 'Tcl error...could not recognize data in image file'. The problem also occurs with other images present in my disk drive.
Here is the code:
from tkinter import *
window=Tk()
window.geometry("420x420")
window.title('My first GUI programme')
source='D:\\Desktop\\op.jfif'
icon=PhotoImage(file=source)
window.iconphoto(True, icon)
window.mainloop()
Here goes the error:
PS D:\Documents\pythonProject> & "C:/Program Files (x86)/Python/python.exe" "d:/Documents/pythonProject/Learning python/Practice.py"
Traceback (most recent call last):

I don't know if there is any problem with my code or i need to change any settings. I would be thankful to you if you provide me any assistance.

I managed to do this by changing the file extension and file content of my image file to 'png' which worked in python.

Python Tkinter supports GIF, PGM, PPM, and PNG. So, try changing the extension of the file to one of them
i see your problem
i also have the same problem

Getting PNGs to Python [duplicate]

I am using Tkinter to write a GUI and want to display a png file in a Tkiner.Label.
So I have some code like this:
self.vcode.img = PhotoImage(data=open('test.png').read(), format='png')
self.vcode.config(image=self.vcode.img)
This code runs correctly on my Linux machine. But when I run it on my windows machine, it fails. I also tested on several other machines (include windows and linux), it failed all the time.
The Traceback is:
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Python27\lib\lib-tk\Tkinter.py", line 1486, in __call__
return self.func(*args)

self.vcode.img = PhotoImage(data=open('test.png').read(), format='png')

self.tk.call(('image', 'create', imgtype, name,) + options)
TclError: image format "png" is not supported
If I delete format='png' in the source code, the traceback will become:

TclError: couldn't recognize image data
So, what should I do to make it support png files?

PIL is now replaced by Pillow http://pillow.readthedocs.io/en/3.2.x/
solution:
from Tkinter import *
import PIL.Image
import PIL.ImageTk
root = Toplevel()
im = PIL.Image.open("photo.png")
photo = PIL.ImageTk.PhotoImage(im)
label = Label(root, image=photo)
label.image = photo # keep a reference!
label.pack()
root.mainloop()
If PIL could not be found in code, you do need a pillow install:
pip install pillow

tkinter only supports 3 file formats off the bat which are GIF, PGM, and PPM. You will either need to convert the files to .GIF then load them (Far easier, but as jonrsharpe said, nothing will work without converting the file first) or you can port your program to Python 2.7 and use the Python Imaging Library (PIL) and its tkinter extensions to use a PNG image.
A link that you might find useful: http://effbot.org/tkinterbook/photoimage.htm

Tkinter 8.6 supports png file format while tkinter 8.5 does not. If you have the option upgrade python and you should be fine to use png.
If you have to use an older version of python you should use Pillow (maintained pil fork) which also works on python3.
If you are starting a new project do not use python2 or PIL as suggested in the accepted answer, they are both depreciated technologies.

Fixed in official python.org 64-bit (only) installer for OS X. Tk version 8.6 is included out of the box. Warning: if you use homebrew, as of this post doing brew install python3 will only give you 8.5, and 8.6 is required to use png so you'll have to use official installer instead. To check which Tk you are using:
$ python3 -c 'import tkinter; print(tkinter.TkVersion);'
If it report 8.6, you are good to go.

from tkinter import *
from tkinter import messagebox
import os
from PIL import Image, ImageTk
root = Tk()
root.geometry("1300x720")
root.title("KEDİLERİMİZ ve KÖPEKLERİMİZ")
class Ana:
def __init__(self,name,roll):
self.name = name
self.roll = roll
resim = Label(root,width=77,height=43,bg="blue")
resim.place(x=730,y=10)
o = "1.PNG"
hu = o.find(".")
mu = o[hu:]
if mu == ".gif" or mu == ".png":
img = PhotoImage(file = o)
else:
photo = Image.open(o)
img = ImageTk.PhotoImage(photo)
resim.configure(image=img,width=img.width(),height=img.height())
resim.image = img

on windows you gotta use this specific format:
Example = PhotoImage(file='photo.png')
and if you wish to resize it to a smaller size:
Example = Example.subsample(2, 2)
or
Example = Example.subsample(3, 3)
Total Code:
Example = PhotoImage(file='photo.png')
Example = Example.subsample(1, 1)
but future warning, you gotta file the file location in with the photo unless you put the photo in the same file as the script!

try with PIL library instead of converting your image to GIF, PGM, or PPM (PhotoImage) only accept these 3 formats.
import tkinter as tk
import PIL.Image
import PIL.ImageTk
base = tk.Tk()
base.title("Dialy Dose")
logoPath = r"C:\Users\saigopi\Downloads\logo.png"
ref = PIL.Image.open(logoPath)
photo = PIL.ImageTk.PhotoImage(im)
inputEdit = tk.Label(base,text="Enter Quote")
save = tk.Button(base,text="Save",background="green",command=save())
logo = tk.Label(base,image=photo,text="Logo bro lite")
quote = tk.Label(base,text="I am saying you are more than something")
inputEdit.pack()
save.pack()
logo.pack()
quote.pack()
base.mainloop()

I used PhotoImage to add my Gui an icon with png format.
Like in below, It can work or give you an idea.
iconn = PhotoImage(file = "arcen.png" )
root.iconphoto(0, iconn)

Python: Can't display images in Zelle graphics.py, tkinter can't read image data

I am trying to display the image "picture.gif" in this code:
from graphics import *
import tkinter
win = GraphWin("Self Portrait", "1000", "500")
image = Image(Point(5,5), "picture.gif")
image.draw(win)
window.mainloop()
However, I keep getting this error:
Traceback (most recent call last):
File "/Users/jstorrke/Desktop/Python/graphicsProject.py", line 6, in <module>
image = Image(Point(5,5), "picture.gif")
File "/Users/jstorrke/Desktop/Python/graphics.py", line 827, in __init__
self.img = tk.PhotoImage(file=pixmap[0], master=_root)

_tkinter.TclError: couldn't recognize data in image file "picture.gif"

The graphics module provides very minimal support for displaying images. Try putting the image on the same folder as where graphics library is and see if it helps.
Please look at this document for more information on graphics module. http://mcsp.wartburg.edu/zelle/python/graphics/graphics.pdf

_tkinter.TclError: couldn't recognize data in image file "picture.gif"
I looked at dozens of examples this error message and the cause seems to fall into two categories:
1) The file wasn't a supported type (e.g. *.jpg, *.png, *.tif) which was obvious from the extension.
2) The file used was mislabeld as a *.gif when it wasn't. (More common than I would expect.) On Unix systems you may be able to use the file command to verify your GIF:
> file p7Q6O.gif
p7Q6O.gif: GIF image data, version 89a, 520 x 416
>
An actual failure of a valid GIF file occurs if it's an animated GIF which are not supported. However, this can be a silent failure -- no error message and no image displayed.

tkinter will not recognize image data in base64 encoded string

I changed from Python 3.4 to Python 2.7, and while debugging my script I found the interpreter unable to read a base64 graphic encoded in a string. I wanted to use the encoded image as a background for a tkinter canvas like so, but I am unable to do so now as I had been with Python 3.4:
background="""
iVBORw0KGgoAAA #....continues
"""
photo = tk.PhotoImage(data=background)
width, height = photo.width(), photo.height()
canvas = tk.Canvas(root, width=width, height=height, bd=-2)
canvas.pack()
canvas.create_image(0, 0, image=photo, anchor="nw")
When I run the script, I get this error:
>Traceback (most recent call last):
File "main.py", line 31, in <module>
photo = tk.PhotoImage(data=background)
File "c:\Python27\lib\lib-tk\Tkinter.py", line 3323, in __init__

Tkinter and PIL not loading jpegs

I'm trying to allow my Tkinter program to load and display .jpgs files from the standard .gif
import Image,ImageTk
root = Tk()
PILFile = Image.open("Image.jpg")
Image = PhotoImage(file=PILFile)
ImageLabel = Label(root,image=Image)
ImageLabel.image = Image
ImageLabel.pack()
root.mainloop()
The error message I get follows:
Traceback (most recent call last):
File "/home/paragon/Programs/Python/Web/MP3Tagger.py", line 25, in <module>
albumart = PhotoImage(file=PILfile)
File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 3271, in __init__
Image.__init__(self, 'photo', name, cnf, master, **kw)
File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 3227, in __init__
self.tk.call(('image', 'create', imgtype, name,) + options)
_tkinter.TclError: couldn't open "<JpegImagePlugin.JpegImageFile image mode=RGB size=1500x1500 at 0x98AEFCC>": no such file or directory
[Finished in 0.4s with exit code 1]
I am absouletly certain that the file exists in the correct format,what could I be doing wrong?

According to The Tkinter PhotoImage Class:
The PhotoImage class can read GIF and PGM/PPM images from files:
....
If you need to work with other file formats, the Python Imaging Library (PIL) contains classes that lets you load images in over 30 formats, and convert them to Tkinter-compatible image objects:
from PIL import Image, ImageTk
image = Image.open("lenna.jpg")
photo = ImageTk.PhotoImage(image)
-> Replace Tkinter.PhotoImage with ImageTk.PhotoImage:
root = Tk()
PILFile = Image.open("Image.jpg")
Image = ImageTk.PhotoImage(PILFile) # <---
ImageLabel = Label(root, image=Image)
ImageLabel.image = Image
ImageLabel.pack()
root.mainloop()

Your error occurs because of the argument file:
Image = PhotoImage(file=PILFile)
This would specify a file path. In addition, you want ImageTk.PhotoImage. Instead, you want:
Image = ImageTk.PhotoImage(PILFile)
