Glad to know it's helpful!!
I should note however that this does not replace using a reverse image search engine, but rather complements using one. It'll find larger versions stored within the website itself (either through URL patterns or API calls), which are sometimes larger than what reverse image search engines can find (unless they crawl a page that contains the original image), but if the original image uploaded on the site is smaller than what's available on another site (e.g. an image reuploaded to a blog), it won't be able find that version.
