[SOLVED] Custom Icons

I think I am still having the problem, Where is the folder location on a RPI

The config folder on RPI is on etc/openhab2

I already created the folder icons/classic with all icons inside in

And add one of the icons in this folder (in my case cd.svg) to an Item

String Sal_Album  "Album [%s]"  <cd >   (AV_Salon, Sonos) channel="sonos:PLAY1:salon:currentalbum"}

But it doesn’t work.
What am I doing wrong ?
