I saw that someone else had photos --or rather, links to photos on their "Tips" page, so I'm keyboarding in this comment, hoping how to do that will become apparent.
What I'd rather do is enter photos that are formatted into the text here.
Hmmnnn: I see no "Help" button. "F1" didn't summon help either.
So okay: best I look at the Journal entry proper --where there are definitely photos and text run together.
