OMG, the names are totally different on AlainK's posting and my posting, where both the thumbs show in both the upload area and in the text area. I'm sure I can't make it do that aberration when I want, but I can check the naming scheme in the text area from different kinds of uploads. Method 1: Click Upload a File, then click Insert every Thumbnail. Edited: Method 1 result looks fine. The mouseover and corner url display names both are the same as my photo names. That is not the case in AlainK's posting at Autumn 2015 pics | UBC Botanical Garden Forums, where the instream names are some temp_hash name.
Method 2: Click Upload a File, then drag the uploaded photos to the instream location where I want them, one by one. Ooh, I have the aberration I want! And this time, the instream names have the temp_hash name.
The thing is, in the Plants ID posting with spleenwort in the name, it's the instream photos that have the right photo name and the thumbs that have a different name. OK, Method 3: drag the photos in from a File Explorer window. Well, they don't end up here automatically, so I will drag them up here, since that's what is shown on the video I'm using for documentation right now. Well, this is the same result as I got previously.
