Do you know how to activate picons in blackhole

Hi there master G
I have managed to get my cccam to work with the cam already installed in blackhole.
But it freezes a lot more (every 5 seconds). Must be where I got my line from. Server must be over subscribed.
Do you know how to activate picons in blackhole. I have downloaded them in the picons downloades section.
But they are not appearing. I have sets of picons that I have got from various sites. So if you cannot help me
with activating the blackhole ones then I will filezilla my lot into the system.
Many thanks for your time.
