Using ms edge:
right click on image to enable.
bottom of menu, left click 'inspect'
left click on three dots, upper left.
left click 'copy'. then 'copy element'
In fr comment, right click, then 'paste'
image size can be manipulated using:
(eg) width="200"height="200" immediately after 'img',
leaving at least blank one space after 'img'

This process works on most images posted on the net.
Doesn't work with 'twitter' images.
re:
(eg) width="200"height="200" immediately after 'img'I would suggest using only width or height, not both. By specifying only width, for example, the browser will resize the picture preserving the width-to-height ratio in the original image.
