Word won't paste images from web?
After copying the image in the web browser, go to Word and click the down arrow on the Paste icon (Home tab), select Paste Special, then select Device Independent Bitmap.
This happens with images that are produced from binary data, in the "data:image/ext;encode,binary" format.
There's nothing that can be done for Microsoft Word but you can use LibreOffice and then past from LibreOffice into Word.
