Show HN: Capture current frame as jpeg via bookmarklet

caveats: no external images, no custom fonts, no other iframes ( but this can be a positive as it removes ads ). Try it on google search result page, github, bloomberg, etc. It produces a 'text only' image of the page. big pages take a while ( 10 - 15 seconds ). some sites ( youtube, flickr ) just give a mostly blank page.
