Archivarix External Images Importer

Works great!
I imported several posts into a site running WordPress 5.9.3 with Gutenberg and the Archivarix External Images Importer plugin imported the external images without any issues. I've tested a few other image importer plugins but none of them had the ability to scan a site and import from existing content like this one does.

Works with Gutenberg

Import external images in posts and pages from its original external sources or Web Archive if original source is unavailable.
