I have drag and dropped saving the pic on my pc then drag and drop from files, I've also dragged and dropped directly and copy and paste from few of substack, but still c/p is the same. Just depends on convenience of the individual. I think the problem has to do with other things than the either way provides. Another thing that when you drag and drop, this site adds code to the image. Here's a clip shot of my post before posting. Different from what I can see in the post. And I don't see the pics that I put img brackets around on my screen, just the code.
