I'd like to take a full-page screenshot of a website, but the single page is a little too long such that there's a scrollbar. The printscreen function don't work here.

Is there any other alternatives?

If you don't have to do this often, just take a few screenshots and combine them.

I goto a comp store hop on a 30incher and take the SS then just email it or ftp it up. :)

What do you mean by doesn't work? When you press the button it doesn't work at all?
