How to save web page as image using python

I am using python to create a "favorites" section of a website. Part of what I want to do is grab an image to put next to their link. So the process would be that the user puts in a URL and I go grab a screenshot of that page and display it next to the link. Easy enough?

I have currently downloaded pywebshot and it works great from my terminal on my local box. However, when I put it on the server, I get a Segmentation Fault with the following traceback:

/usr/lib/pymodules/python2.6/gtk-2.0/gtk/__init__.py:57: GtkWarning: could not open display
  warnings.warn(str(e), _gtk.Warning)
./pywebshot.py:16: Warning: invalid (NULL) pointer instance

  self.parent.show_all()
Segmentation fault

I know that some things can't run in a pts environment, but honestly that's a little beyond me right now. If I need to somehow pretend that my pts connection is tty, I can try it. But at this point I'm not even sure what's going on and I admit it's a bit over my head. Any help would be greatly appreciated.

Also, if there's a web service that I can pass a url and receive an image, that would work just as well. I am NOT married to the idea of pywebshot.

I do know that the server I'm on is running X and has all the necessary python modules installed.

Thanks in advance.

Solution

  • I found websnapr.com which is a web service that will give you the image with just a little bit of work.

    import subprocess
subprocess.Popen(['wget', '-O', MYFILENAME+'.png', 'http://images.websnapr.com/?url='+MYURL+'&size=s&nocache=82']).wait()

    Easy as pie.
