The images used to be generated by http://stachu.cubing.net/v/visualcube.php which also used to generate the images for algdb. It seems that's not up at the moment. The easiest alternative is to paste the algorithms into alg.cubing.net to see which case they solve. I had an alg sheet, but it has worse algs than gyroninja's and also uses stachu's version of visual cube, so it's not much use at the moment either.I'm wanting to learn zz-ct, after learning normal ZZ with PLL + OCLL, but all the images on the main page for algorithms is gone. What happened, and are there any alternative alg sheets available?
