Take a screenshot of all bookmarks in google chrome?
Dependencies: grep, sed, webkit2png (or khtml2png)
1) Export your bookmarks from Chrome to ~/bookmarks. They'll be exported in an XML format.
2) get a list of URLs from the file (use xmlstarlet if you want something more proper than this grep hack) and pipe to webkit2png if on mac or khtml2png if on linux:
cat ~/bookmarks | grep -oE 'A HREF="[^"]+"' | sed -e 's/^A HREF="//' -e 's/"$//' | while read URL; do webkit2png "$URL"; done
