Sorry, don’t know how on this site.
Right-click on the image then select ‘properties’ to get the source url. copy it and paste it between the quotation marks in the code below, then copy and paste the whole thing into the reply section and hit preview. You’ll need to add the closing > at the end so it’ll work. I can’t add it in my reply to you without it trying to create a blank picture instead of showing the code itself.
<img src=” “ /
If you did it right it should show the picture in the window and you can post it. I keep a copy of the blank code saved as a Word doc so it’s always at the ready for plugging in photo info. Good luck to you.
