What is the easiest way to show a .jpg or .gif image from Python console?

I've got a Python console program that is checking a data set which contains links to images stored locally. How should I write the script so that it would display images pop-up graphical windows?

Using the awesome Pillow library:

>>> from PIL import Image                                                                                
>>> img = Image.open('test.png')
>>> img.show() 

This will open the image in your default image viewer.

In a new window using Pillow/PIL

Install Pillow (or PIL), e.g.:

$ pip install pillow

Now you can

from PIL import Image
with Image.open('path/to/file.jpg') as img:
    img.show()

Using native apps

Other common alternatives include running xdg-open or starting the browser with the image path:

import webbrowser
webbrowser.open('path/to/file.jpg')

Inline a Linux console

If you really want to show the image inline in the console and not as a new window, you may do that but only in a Linux console using fbi see ask Ubuntu or else use ASCII-art like CACA.

Since you are probably running Windows (from looking at your tags), this would be the easiest way to open and show an image file from the console without installing extra stuff like PIL.

import os
os.system('start pic.png')

In Xterm-compatible terminals, you can show the image directly in the terminal. See my answer to "PPM image to ASCII art in Python"

ImageMagick's "logo:" image in Xterm (show picture in new tab for full size viewing)

You cannot display images in a console window. You need a graphical toolkit such as Tkinter, PyGTK, PyQt, PyKDE, wxPython, PyObjC or PyFLTK. There are plenty of tutorial how to create siomple windows and loading images iun python.

Why not just display it in the user's web browser?

Or simply execute the image through the shell, as in

import subprocess
subprocess.call([ fname ], shell=True)

and whatever program is installed to handle images will be launched.

If you would like to show it in a new window, you could use Tkinter + PIL library, like so:

import tkinter as tk
from PIL import ImageTk, Image

def show_imge(path):
    image_window = tk.Tk()
    img = ImageTk.PhotoImage(Image.open(path))
    panel = tk.Label(image_window, image=img)
    panel.pack(side="bottom", fill="both", expand="yes")
    image_window.mainloop()

This is a modified example that can be found all over the web.

You can also using the Python module Ipython, which in addition to displaying an image in the Spyder console can embed images in Jupyter notebook. In Spyder, the image will be displayed in full size, not scaled to fit the console.

from IPython.display import Image, display
display(Image(filename="mypic.png"))

I made a simple tool that will display an image given a filename or image object or url.
It's crude, but it'll do in a hurry.

Installation:

 $ pip install simple-imshow

Usage:

from simshow import simshow
simshow('some_local_file.jpg')  # display from local file
simshow('http://mathandy.com/escher_sphere.png')  # display from url

If you want to open the image in your native image viewer, try os.startfile:

import os

os.startfile('file')

Or you could set the image as the background using a GUI library and then show it when you want to. But this way uses a lot more code and might impact the time your script takes to run. But it does allow you to customize the ui. Here's an example using wxpython:

import wx
 
########################################################################
class MainPanel(wx.Panel):
    """"""
 
    #----------------------------------------------------------------------
    def __init__(self, parent):
        """Constructor"""
        wx.Panel.__init__(self, parent=parent)
        self.SetBackgroundStyle(wx.BG_STYLE_PAINT) # Was wx.BG_STYLE_CUSTOM)
        self.frame = parent
 
        sizer = wx.BoxSizer(wx.VERTICAL)
        hSizer = wx.BoxSizer(wx.HORIZONTAL)
 
        for num in range(4):
            label = "Button %s" % num
            btn = wx.Button(self, label=label)
            sizer.Add(btn, 0, wx.ALL, 5)
        hSizer.Add((1,1), 1, wx.EXPAND)
        hSizer.Add(sizer, 0, wx.TOP, 100)
        hSizer.Add((1,1), 0, wx.ALL, 75)
        self.SetSizer(hSizer)
        self.Bind(wx.EVT_ERASE_BACKGROUND, self.OnEraseBackground)
 
    #----------------------------------------------------------------------
    def OnEraseBackground(self, evt):
        """
        Add a picture to the background
        """
        # yanked from ColourDB.py
        dc = evt.GetDC()
 
        if not dc:
            dc = wx.ClientDC(self)
            rect = self.GetUpdateRegion().GetBox()
            dc.SetClippingRect(rect)
        dc.Clear()
        bmp = wx.Bitmap("file")
        dc.DrawBitmap(bmp, 0, 0)
 
 
########################################################################
class MainFrame(wx.Frame):
    """"""
 
    #----------------------------------------------------------------------
    def __init__(self):
        """Constructor"""
        wx.Frame.__init__(self, None, size=(600,450))
        panel = MainPanel(self)        
        self.Center()
 
########################################################################
class Main(wx.App):
    """"""
 
    #----------------------------------------------------------------------
    def __init__(self, redirect=False, filename=None):
        """Constructor"""
        wx.App.__init__(self, redirect, filename)
        dlg = MainFrame()
        dlg.Show()
 
#----------------------------------------------------------------------
if __name__ == "__main__":
    app = Main()
    app.MainLoop()

(source code from how to put a image as a background in wxpython)

You can even show the image in your terminal using timg:

import timg

obj = timg.Renderer()                                                                                               
obj.load_image_from_file("file")
obj.render(timg.SixelMethod)
