I'm not sure why your pictures are not showing up. I'm going to experiment.

O.K. that seems to work. I dragged and dropped it and I see it. Now to check whether others can also see it! This is a picture of my two girls, taken a long time ago......probably in the '80s.

I am wondering if the picture you are trying to upload is too big. Trying that now. I am not seeing the picture I just uploaded, so that may be the problem.

Yes, I think that is the key. Downsize your picture and I bet it will work properly. As you see, I get the same uploading message that you did, but no picture, when I try to upload a large file.
