Does Not Work in 4.1?

The exact instructions are:

– Create a new post, and add a link to a test image (such as one on your Flickr account).
– Now click the “Save Draft” button.
– If your editor is in HTML mode, you will see that the SRC attribute has changed.
– If not, you can click on the Add Image icon and you will see a new image has been added to the Gallery for this post.

But when I pasted the link, it just laid there and did nothing. No picture appeared, and no image was added to the gallery.

So if it is 2015 or later, you should probably look for another plugin.
