My PC allows me to copy the image but not to paste it.Go to page 57 of this thread and you'll find a post with a star in it. Place your curser immediately to the left of it and left-click your mouse to highlight it. Right-click and select the choice: Copy. Go to the top right of this page and 'hover' your curser over your name. From the list on the left-hand side that drops down, select Signature. In the panel that appears, right-click and select Paste. Just add what it's for, and click save. Ta-da!
It only allows me to paste it as a link. Any idea why?
