Custom skin icons / buttons

Hello,

I would like to change the ‘linked’ icons in mAirlist 7, but i can’t seem to do so.
I created an /images folder in the mAirlist folder and placed an ‘icon_linked.png’ in there, but it does not work. I also have mAirlist 6.3 still installed, and if i do the same there it works.

Dit something change in 7? I can’t find it anywhere on the forums.

Kind Regards,
Max.
