So im new to secondlife and I've been working my way around learning, taking freebies, etc. I got some makeup and tattoo freebies, and they are a texture. I dont know how to apply this texture to my avatar. I've tried selecting my body and going to the edit mode and going to textures, but a little lock pops up over the texture box. Do i have to take my Slink body off or select an option in the SLink body hud??
