I made a few changes to pkShow, I added a remote control with indicators for the set. plus I added settings allow you any combination of 10 or 20 slides with 10 or 20 seconds. this way you have 1:40min, 3:20min or 6:40min set.
you can download the latest copy here.
I moved the server, when I did that I shutdown a lot of old DNS addresses and related site I don’t use anymore. So I updated the link above so you can actually download the software. If you run into that elsewhere, let me know and I’ll fix the link.
