Geoff,
I'm practicing on some of the features here and although am not posting a picture at this time, I am trying to figure it out. The couple times I did post a picture, I just knew how to post the link, and viewers would have to click the link.
When I am in the "reply" screen, I click the "enter an image" icon and I get this message under my browser:
"This website is using scripted windows to ask you for info. If you trust this website click here to allow scripted windows." I assume that's normal??? And, not that I post pictures often, but should I post one, I'd click to "allow"?????
