Create Webpage Images in less than 4 seconds.

Hello, I want someone to implement Code to Convert Webpage to JPG? Image. My Requirement is that this be done in less than 4seconds per web page request. I have high speed internet where a Webpage load in less than 4seconds. Hence I am Hoping to do this in approximately the same amount of time. There are several sites that have a service like this. Some examples are? <[login to view URL]> <[login to view URL]> <[login to view URL]> These do not meet my requirments since they do not have an image? for every possible site. Hence I would like someone to write code that will do this for me. Create a JPG file for the site on the fly. The Image size will be approx 400x400 and quality wise it should be good enough so that the user can an idea of the content on the site corresponding to the image. I need this to be a web application. There will be a Text box and a submit button, The User Enters the site url and clicks submit. The Application should display the resulting image in less than 4 sec. You will also have to display the time it took to generate? the image. Thanks, Akash
