Hi I'm developing a website and I was wondering if anyone knew a way where I can automatically retrieve a homepage screenshot of a website a user posts? For example, when someone enters their URL, I'd like it so that my site automatically retrieves a screenshot of the homepage and resizes it. Basically what Alexa is able to do. Thanks for the help in advance!
you will either need to wrap a browser like IE in an application or control a browser with an application - either way, you want to use the power of the browser to render the html, then capture the bitmap data.
try snap.com, they provide such service, where in you can have tooltip image displayed about the website url.
Can this be useful for you? If you know some php, this is probably the best/free solution for you. http://www.phpclasses.org/browse/package/918.html
