Ron,
I think the problem in this case may be you are viewing the picture on the computer directly from the google account, yes???
Because your google folder seems to require you to sign in to view (?), you need to copy and save the picture to your computer (like in the "download directory"). Once it's saved to your computer, add the picture to the post using the "Attachment manager" process, using the file location from your computer - not the google account.
Just trying to help my friend.
