This is bizarre. Yesterday none of @Rikki Gins images showed up for me. Now they appear.
I'm no expert
@JUAN, but I think it has something to do with my image host, Postimage. When they go down for any reason such as for routine maintenance, or a power outage, or if their whole system just happens to go down, then no images appear and likewise, as happened a few nights back, one can't use them for creating an image. Well, I guess you get what you pay for, and in this case, I'm paying nothing for their service.
