My images are copied into the "public" folder of my M$ Cloud, after which I copy the link to the image and put it between the
balises.
So far, so good, images are correctly resized and the original can be viewed.
Problem is, when I go back to the thread a few hours later, the image is no longer visible. The image is still there on OneDrive, but the address has changed.
Bottom line: OneDrive is not Flicker. I'll have to find another solution. Sorry for the inconvenience, there are already three cases here.
