Image Spotter

This code is a simple script designed to be executed as a bookmark while surfing the web. When it's run, it prints an overlay with the images found on the current website, which can be downloaded when you click on them.

Users can grab the bookmark from the page https://patillades.github.io/img-spotter/ or generate it manually, making sure it contains the corresponding JavaScript code as a link. If the website where you are trying to use the bookmark uses the "script-src" content security policy rule to prevent scripts from being loaded from foreign domains, then the script will not work.
