Trial
OK great, that worked.
But I couldn’t get it to work with a different image
So I think the issue here is that I actually don’t know how to get the URL for images. Again this is something I rarely do, so I may be wrong about this being the problem.
What I tried was doing a Google search for images, selecting one I liked, selecting the Share menu in Safari, copying the link it provided, and pasting it here. I don’t think that procedure yields a URL for just the image. I tried to find something online to learn how to get to the picture-only URL but couldn’t find anything that gave me an instruction that led to success in accomplishing what I wanted.
Basically I post images usually to just add a bit of levity to a thread, so it’s not huge to me to lose this capability. I’ll look forward to checking things out following the above-refernced improvements. Thanks!
