Is there any script or software that can generate website's screenshot in a thumbnail and then display it on my site. What i want it to do is for my users to be able to enter their web URL and their website's thumbnail screenshot would show in their profile page. Something like alexa does. How can this be done?
we build apps in ruby on rails, if we need to generate thumbs we use the blgua web api http://webthumb.bluga.net/home
