Simple instructions on how to programmatically download an image from a web page?

[Y2KYZFR1]

I have search the group and not found a working example on how to
simply download a .gif from a url.

something as simple as
http://groups.google.com/images/threadview_logo.gif should be pretty
easy, guess not?

I don't need to know about using a browser, I need to know how to do
it programmaticall y from Python.

Anyone know how to get it done?

I guess you didn't think to search the documentation too ;-).

Try the urllib.urlopen function.

I just tried this interactively some example lines from httplib
(the if 1: was just to execute the indented lines in one go)
[color=blue][color=green][color=darkred]
>>> import httplib
>>> if 1:[/color][/color][/color]
... conn = httplib.HTTPCon nection("www.py thon.org")
... conn.request("G ET", "/pics/PythonPoweredSm all.gif")
... r1 = conn.getrespons e()
... print r1.status, r1.reason
... data1 = r1.read()
...
200 OK[color=blue][color=green][color=darkred]
>>> len(data1)[/color][/color][/color]
361[color=blue][color=green][color=darkred]
>>> data1[:8][/color][/color][/color]
'GIF89a7\x00'[color=blue][color=green][color=darkred]
>>> file('pypowgif. gif','wb').writ e(data1)
>>> import os, webbrowser
>>> webbrowser.open _new(os.path.ab spath('pypowgif .gif'))[/color][/color][/color]

or using windows file association, also
[color=blue][color=green][color=darkred]
>>> os.system(os.pa th.abspath('pyp owgif.gif'))[/color][/color][/color]

You should check errors etc., but the data apparently got through
(not the logo you asked for though ;-)

It's trivial with urllib.
