Rails 3: page render to preview image

Is there a way in rails 3, on server side to render a png or jpg of any given page in my rails app and store it? I'd like to do something like the preview that google uses in the google search when you mouse over the magnifying glass, but only within my app. I'm currently making use of paperclip and imagemagik in 开发者_StackOverflowmy app. Thanks

The only ruby based thing I found was websnap. I never got it to run reliably (especially when there is Flash involved).
