What is the best way to create a web page thumbnail?

Question

Is there some reasonably cross platform way to create a thumbnail image given a URL? I know there are thumbnail web services that will do this, but I want a piece of softwar

Answer 1

You can use Firefox or XULRunner with some fairly simple XUL to create thumbnails as PNG dataURLs (that you could then write to file if needed). Robert O'Callahan has some excellent information on it here:
