... but as far as I can tell, this page doesn't provide any option expect to use images from /graphics.dir/alfaeriePNG35/.
Indeed, this page focuses on game rules, not on presentations. (The Diagram Editor with Scalable Graphics served that purpose.) And I did not needlessly want to complicate the interface with non-essentials, as this might scare off people.
But one can paste an existing Diagram made by other means into it. And in that case it would inherit all settings of that Diagram, even those that it could not create through the user interface on the page.
Since the output of the page is text to be copy-pasted elsewhere it is always possible to post-edit it. It would even be possible to use a design cycle that consists of first requesting the Diagram HTML from the Applet, edit that in the window where it appears, e.g. to alter graphicsDir, and then paste it back and ask for GAME code.
