This is relative to the path of the current file (which is the JS file
itself), so you should put the /img folder inside the /static/js folder.

Note, URL() is a Python function that works only on the server in the
web2py environment -- you cannot insert it into a static JS file, which is
executed entirely within the browser.

If you want to keep the file in /static/img, you can still use a relative
URL:
cfg.pieceTheme = '../img/chesspieces/wikipedia/{piece}.png
<http://127.0.0.1:8000/tablero/static/img/chesspieces/wikipedia/%7Bpiece%7D.png>
';
The ../ will traverse from the /js folder up one level to the /static
folder.
