I am trying to start a new topic and post a picture that I uploaded to a free image site. When I click the picture icon, it asks for URL. I enter URL and then I see a broken picture icon, which I assume means that system can't post the picture. And I don't see any preview option before posting (didn't there used to be one?) so I can't check whether my picture is going to be visible or not. I would post it anyway but I'm not sure I can delete it if the image fails to appear.
When I search forum for help on this issue, I find a lot of irrelevant posts with no solution. I hope someone can enlighten me.
