Wouldn't link properly for me either with just the image address you used. So I looked at the image address you were trying to post. I opened the link and right clicked on the image and noticed that there was no option for save image or copy image address, just open link or copy link. So I opened link in a new tab. Right clicked on that image and could then copy the image address which was different, and apparently linkable using the image tags. Not sure why the extra step is needed, but the original image address doesn't seem to allow direct image linking. You need to get the image by itself to copy and paste with IMG tags.
So started with this address:

And ended up with this address:
