Image Sourcer is a browser plugin that can be used to pull up a list of the images used on a page at a given time. Useful for comparing assets without having to dive into the browser console.
Available for Free in the Chrome Web Store
The build process is run thru a simple shell script, as opposed to some amalgam of javascript libraries and modules. It does use NPM, though. You can build the plugin with:
./build.sh
