That is what I remember!
Also from what I remember (and my memory is not good!) the [Caption] is more like an ALT text. I think it is called a tool tip and it pops up after a few moments. ![Caption](/image.png) would be easier to remember for people that had used markdown.
No this is not markdown.
Markdown would be ![Caption](/image.png).
Would you prefer that syntax? Is that better?
