Okay, thanks Bruce. What type of pc and operating system are you using?
I think the gremlin on my machine is part of a Windows 10 update a few days ago. It was a massive update and I suspect that my issue started with that. BTW, I have been following the procedures you referred to for pictures for sometime and haven't struggled until this gremlin surfaced.
I have been resizing photos with different Microsoft programs and it shows that they are jpeg files when done. Properties say it is a jpeg with a certain file size. For example, the above photo was saved to my desktop but it would not load from my machine. It did from yours.
I tried a new twist and it seems to be necessary to my system now. Even though the previous files were jpegs, I am not sure the upload process recognized them as such from my machine as I tried to upload them. I just resaved one by selecting jpeg from a drop down and while the properties didn't change, it now uploads. So my problem is solved. Thanks for trying to help.
I will call it Windows 10 update issues and move on. It just adds an additional step on my pc to make it work.
