response = requests.get(url, stream=True)

# image_viewer.pyimport io
import os
import PySimpleGUI as sg
from PIL import Image
file_types =[("JPEG (*.jpg)","*.jpg"),("All files (*.*)","*.*")]defmain():
    layout =[[sg.Image(key="-IMAGE-")],[
            sg.Text("Image File"),
            sg.Input(size=(25,1), key="-FILE-"),
            sg.FileBrowse(file_types=file_types),
            sg.Button("Load Image"),],]
    window = sg.Window("Image Viewer", layout)whileTrue:
        event, values = window.read()if event =="Exit"or event == sg.WIN_CLOSED:breakif event =="Load Image":
            filename = values["-FILE-"]if os.path.exists(filename):
                image = Image.open(values["-FILE-"])
                image.thumbnail((400,400))
                bio = io.BytesIO()
                image.save(bio,format="PNG")
                window["-IMAGE-"].update(data=bio.getvalue())
    window.close()if __name__ =="__main__":
    main()

Ejemplo 3: visor de imágenes pysimplegui

import PySimpleGUI as sg
import os

# Simple Image Browser based on PySimpleGUI# Get the folder containing the images from the user
rc, folder = sg.GetPathBox('Image Browser','Image folder to open', default_path='X:/- EBAY - Gruen/Images - Oct Nov Dec 2017')if rc isFalseor folder is'':
    sg.MsgBoxCancel('Cancelling')
    exit(0)# get list of PNG files in folder
png_files =[folder +'\'+ f for f in os.listdir(folder)if'.png'in f]
filenames_only =[f for f in os.listdir(folder)if'.png'in f]iflen(png_files)==0:
    sg.MsgBox('No PNG images in folder')
    exit(0)# create the form that also returns keyboard events
form = sg.FlexForm('Image Browser', return_keyboard_events=True, location=(0,0), use_default_focus=False)# make these 2 elements outside the layout because want to "update" them later# initialize to the first PNG file in the list
image_elem = sg.Image(filename=png_files[0])
filename_display_elem = sg.Text(png_files[0], size=(80,3))
file_num_display_elem = sg.Text('File 1 of '.format(len(png_files)), size=(15,1))# define layout, show and read the form
col =[[filename_display_elem],[image_elem],[sg.ReadFormButton('Next', size=(8,2)), sg.ReadFormButton('Prev', size=(8,2)), file_num_display_elem]]

col_files =[[sg.Listbox(values=filenames_only, size=(60,30), key='listbox')],[sg.ReadFormButton('Read')]]
layout =[[sg.Column(col_files), sg.Column(col)]]
button, values = form.LayoutAndRead(layout)# Shows form on screen# loop reading the user input and displaying image, filename
i=0whileTrue:# perform button and keyboard operationsif button isNone:breakelif button in('Next','MouseWheel:Down','Down:40','Next:34')and i <len(png_files)-1:
        i +=1elif button in('Prev','MouseWheel:Up','Up:38','Prior:33')and i >0:
        i -=1if button =='Read':
        filename = folder +'\'+ values['listbox'][0]# print(filename)else:
        filename = png_files[i]# update window with new image
    image_elem.Update(filename=filename)# update window with filename
