BUG: Macro to insert URL image in Notes is not correct

Via Windows GUI, I can insert an image in a topic Note without problems, both an image from a local file and an online image via its URL.

Trying to insert an image in a topic Note via a macro goes well if I use a local file. It works strange if I use a URL.

What did I do:

1. I created a macro to insert an image by URL in the selected topic.
2. Wheb I run the macro, the result is an empty frame is inserted in the Note.
3. The empty frame has a popup menu. The menu actions are as follows:
4. save image: error message: cannot find this file (and it lists the correct URL)
5. format image: shows link to source image (that same URL)
6. refresh image: cannot find this file
7. reset image size: cannot find this file
8. I exported the mindmap to MS Word: now the picture is present!
9. I exported the mindmap to webpages: now the picture is present as well (beit as GIF and not as PNG)
   My conclusion: The macro for adding a web image to a topic note does not render the image, although it "knows" the correct URL as a reference to the source.
   

Please, advice.
