embedded Web render component?

I had some success coming up with a bash script on my Ubuntu computer to do the "proxy-rendering" task. It uses system packages cutycapt and imagemagick. For testing on my home network I ran "webfsd" from the webfs system package (and poked the right hole in the computer firewall). I'm thinking a script like this would be automatically run periodically, like once every ten minutes, or run from the command line immediately if necessary.

#!/bin/bash
SERVE_DIR=~/Documents
MAX_INDEX=1
URLS=("http://news.yahoo.com/" 
   "http://www.google.com/")
PICS=("yahoo_news" 
   "goog")
  
for ((i = 0; i <= MAX_INDEX; i++)); do
   cutycapt --url=${URLS[i]}  --out=/tmp/${PICS[i]}.orig.png
   convert -gravity North -crop 640x480-0-0 /tmp/${PICS[i]}.orig.png $SERVE_DIR/${PICS[i]}.png
done
