Unexpected response code: 403 when pasting an image

I’ve seen this thread but didn’t see a resolution, so here’s my attempt to take it further.

Similar issue. When copy-pasting some images into anki (right click → Copy Image), it gives the error “Unexpected response code: 403”, and then pastes a link to the image (which Anki seems to parse and display the image) instead of downloading a copy of the image.

It happens with this image, taken from this paper.

When I paste it into Anki, the resulting html is:

<img alt="Level of amputation for lower limb." src="https://www.researchgate.net/profile/Samreen-Hussain/publication/337261018/figure/fig3/AS:825199733776387@1573754356874/Level-of-amputation-for-lower-limb.png">

OS: Windows 10 or 11
Anki 2.1.54
Issue persists in safe mode
Issue persists when copying image from firefox or chrome

Let me know if I’ve missed something!

The website you’re pasting from is blocking Anki’s request.
