Adding custom derma images serverside.

[DarkAura]

So I have a menu, a vtf and png of an image I want to use in a derma frame. However, how do I import the image as to not have it be a missing texture, I want it to show as my custom image on the derma panel for a player.

resource.AddFile or Workshop Addon Creation

I've already done that, like so:
resource.AddFile("materials/merchead.vtf")
L:\Steam\steamapps\common\GarrysMod\garrysmod\lua\entities\mercenaryshop\materials
That is the path, and I am using SetMaterial("materials/merchead.vtf")

I believe the file should be located in the server's material's folder, not the lua folder. So:
L:\Steam\steamapps\common\GarrysMod\garrysmod\materials\merchead.vtf
unless you stick it in a subfolder like you do in the provided example, in which case:
L:\Steam\steamapps\common\GarrysMod\garrysmod\materials\mercenaryshop\merchead.vtf
