Python - Open image within Tkinter from URL - not using PIL

I need to display images within a tk window, but can only use these functions to do it;

from urllib.request import urlopen
from re import findall, MULTILINE, DOTALL
from webbrowser import open as webopen
from os import getcwd
from os.path import normpath
from tkinter import *
from sqlite3 import *
from datetime import datetime

I was thinking that there might be some way I can do this just through tkinter's standard functions, but have yet to find any possible way.

This or I could try and find a way to convert the image to a GIF. Note that no images can be stored on the system.

The images I need to display are either JPGs or PNGs, such as this one.

Any help is appreciated.

The Tcl/Tk module Img allow you to load JPEG and PNG (among other formats) with PhotoImage. This module is included in some packaged distributions of Tcl/Tk. So it is worth checking whether it is installed on the computer you are using. To do so, try to load it with:

widget.tk.eval('package require Img')

widget can be any Tkinter widget.

If it returns a version number, then it is installed and loaded so you can use it and open JPEG images simply doing

PhotoImage(file='/my/image.jpg')

As is stated here:

The PhotoImage class can read GIF and PGM/PPM images from files:

photo = PhotoImage(file="image.gif")

photo = PhotoImage(file="lenna.pgm")

The PhotoImage can also read base64-encoded GIF files from strings. You can use this to embed images in Python source code (use functions in the base64 module to convert binary data to base64-encoded strings):

And as was pointed out in the comments below and here you can also use PNG images with PhotoImage.

Images in tkinter have to be passed in as PhotoImage objects to be drawn and in order to get a PhotoImage object, the image has to be one of the above formats.

So you will need to find a way to get the images in one of those formats using the modules you have available.
