Django thumbnails from urls

I have this Wordpress.com site with thumbnails of themes. I thought about creating a similar site with Django. Instead of using the thumbnail images from the Wordpress gallery as开发者_如何转开发 in the page above, I want to have thumbnails of actual blogs. Is there a way to display thumbnails from urls?

Thank you.

There's nothing django-related here, consider this question How can I take a screenshot/image of a website using Python?
