Thank you. I don’t remember the preview button, but I will definitely try it.
That or use this site:
Click right on your image, hit “copy image address”
Go here:
Hit “upload by URL”, right click to paste your image into the field - then click on the category “hotlink for websites” - which automatically copies it for you. “Command V” to post image onto your FR comment.
So ridiculously easy that even a low-tech normie like me can do it - I don’t have to get my tech-employed son to help me.
