First time, I pasted in the link, then hit IMG. Gave what appeared to be the right sequence, but didn't work. Second time, I FIRST hit IMG, then pasted the link, then hit IMG again. Both ways seem to produce the same results, but neither showed up as an image.
Somebody tell me what's in YOUR string of letters/numbers BEFORE you hit submit, as compared with my 2 examples above. Or do I need to add a .jpg? (The original image was saved as .jpg.)
