How to display an image from web ?

Question

I have written this simple script in python:

import gtk

window = gtk.Window()
window.set_size_request(800, 700)

window.show()
gtk.main()

now I want to load in this window an image from web ( and not from my PC ) like this:

http://www.dailygalaxy.com/photos/uncategorized/2007/05/05/planet_x.jpg

How can I do that ?

P.S. I don't want download the image ! I just want load the image from the URL.

Answer 1

1. Download the image. Google on how to download files with python, there are easy-to-use libraries for that.

2. Load the image into a widget. Look up how to display an image in GTK.

Sorry for the lack of detail, but the answer would get long and you'd still be better off reading on those subjects somewhere else.

Hope it helps!

Answer 2

Here's a simple script using WebKit:

#!/usr/bin/env python
import gtk
import webkit

window = gtk.Window()
window.set_size_request(800, 700)
webview = webkit.WebView()
window.add(webview)
window.show_all()

webview.load_uri('http://www.dailygalaxy.com/photos/uncategorized/2007/05/05/planet_x.jpg')

gtk.main()

Take note, though, that this does in fact download the image.

This downloads the image from a url, but writes the data into a gtk.gdk.Pixbuf instead of to a file:

import pygtk
pygtk.require('2.0')
import gtk
import urllib2

class MainWin:

    def destroy(self, widget, data=None):
        print "destroy signal occurred"
        gtk.main_quit()

    def __init__(self):
        self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
        self.window.connect("destroy", self.destroy)
        self.window.set_border_width(10)
        self.image=gtk.Image()
        response=urllib2.urlopen(
            'http://www.dailygalaxy.com/photos/uncategorized/2007/05/05/planet_x.jpg')
        loader=gtk.gdk.PixbufLoader()
        loader.write(response.read())
        loader.close()        
        self.image.set_from_pixbuf(loader.get_pixbuf())
        # This does the same thing, but by saving to a file
        # fname='/tmp/planet_x.jpg'
        # with open(fname,'w') as f:
        #     f.write(response.read())
        # self.image.set_from_file(fname)
        self.window.add(self.image)
        self.image.show()
        self.window.show()

    def main(self):
        gtk.main()

if __name__ == "__main__":
    MainWin().main()
