问题
Google, Facebook and some others now have a preview link functionality where you can view a "screenshot" of say a website's home page. Are there any suggestions how I can achieve this?
Specifically I'd like to be able to grab a screenshot (a la iPhone screen shot) and make it available as an image such as a jpg or png.
I want to do this from python if possible.

We're using the service Bluga, it's not too expansive and is pretty easy to implement. If you don't like that there are many other services available.

For that you have to run a separate web browser and then save the image in the required format. You may try a headless web stack like phantomJS as a separate process and capture its out put as image.
There are several web services that provide this functionality like WebSnapr

Jquery Preview may also help. It is really similar to Facebook's preview
