A few years ago, I used a Chickenfoot-plugin go from to take screenshots from a lot of sites. This is useful e.g. when you have an ip-range or a list of URLs, and what to make a quick assessment (see any tomcat admin consoles?) of what is running on the servers.
Anyhow, Chickenfoot didn’t keep up with Firefox updates, and stopped working. So I made this little replacement, which runs in phantom js.
First, I checked out the existing imagecaptures, however they were embarrassingly naïve. This little fella has paralell fetching of images, where paralellism can be set, it defaults to 50 - if set too high I’ve found that phantomjs crashes on linux with a “too many open file handles” error.
