I'm not computer saavy. I have an old picture I scanned that I want to post. It's not on my Smartphone, it's not on Photobucket, it's not on Facebook, it's not a youtube video. It's just a simple JPG on my desktop. How do I post it on a thread? I can't seem to copy and paste, and I can drag and drop it. What am I doing wrong (other then being computer illiterate).
