Free Website Thumbnails By BitPixels

I wanted to have thumbnails for the blogs listed in my site 'Free Bloggers Directory', and of course for free, so I started trying some best known services but not found myself satisfied with them. Then I started googling the web and found an awesome, and I think it won't be wrong to consider it as the simpliest, such service provided by BitPixels.com. Moreover, it generates the thumnail instantly and is powered by Google App Engine. It gives upto 1 million free thumbnails a month, no ads, all urls are hosted and the most important part is that it integrates easily with your site or blog.
