Interesting. If you click the + button on the upper left side of the new WordPress.com block editor it gives you a list of possible things to add to the post. One of those options is to pull an image directly from Flickr. How cool is that? Someone out there treating my favorite photography site as if it actually exists? Crazy!
Of course you can also just post a link to an image page directly into the text and it will automatically pull in the image. So… I guess it doesn’t matter at all. Either way is fine.
