Here's a post with a bit of history. In case there was doubt, it wasn't my imagination that I/other(s) had been allowed since long ago to use drawdiagram.php to display individual pieces in submissions:

"Since some contributors have been using drawdiagram.php to display individual pieces, I have made a couple changes.
When drawdiagram.php is used to display a single piece image, it will not display coordinate labels.
The Diagram Designer now includes code you can cut and paste for displaying the piece images used in your diagram. This code places piece images within FIGURE.piece tags with a caption, and I have added CSS to the global css files for formatting the piece class for FIGURE..."
[edit:
Where did I more recently get the idea I was no longer allowed to display individual pieces my old way?:

edit2: to be fair, displaying an individual piece with shortcodes these days (don't think it was always an available option) is fairly easy (once I saw Fergus' example on my rules page), I hadn't noticed that method. Displaying individual pieces with the showpiece.php script (or whatever Fergus' old way was, if different), on the other hand, is a process I never understood, and it seemed lengthy however it is done.
