Where on alexa.com does it do this?
I tried to do this a while ago but didn't have too much success. I could do it on a linux server by calling a shell command that fired up w3m-img (a command line browser that can display images) then running a command line capture script, but the results were rubbish to say the least
I'd image this is alot easier on a windows server, as you could just fire up windows apps to handle the capturing ?, and there's plenty of windows apps that do this.
Thanks for writing. Ok, if you goto Alexa.com and search Forums.devnetwork.net for example, go down the page to Correct errors and omissions in this listing. When you click on Correct, it takes you to a page that has Update Thumbnail Image of devnetwork.net.
Hmm..if you think about it, it's probably pretty obvious. As the screenshots arn't created 'instantly' then there's no reason they couldn't just be running some 'offline' program.
This is how i used to do it, i wrote a browser in delphi that would accept a list of url's and then merrily go off any take screenshots of them all and dump them in a directory. But being able to type a url in a text box and have it instantly/dynamically generate a screenshot (online) would be nice.
