I have changed nothing with my camera and am attempting to up-load the way I was always successful at before. Just tried it again and was unsuccessful! I have PMed Bob about my problem and my guess is he is fully aware of the problem. Before I came to the Model Railroad Forum I participated at Railroad Line Forums and they had a complicated way of up-loading photos and that was the reason I quit that forum. I wouldn't mind if using photos was left out of the game here at MRF! However, it does diminish the usefulness of the forum!
Interestingly, the problem with Safe browsing manifested itself on 9/19/2017. However, the last photo posted here was on 9/30/2017, 11 days after!
ModelBob made a statement that the website was clean as of 9/25/2017.
