how to sell head if someone is interested for example: "i bid 1k" and i said deal send the tc first then you will get the head... so how do i send the head to the buyer??
Don't confuse him, he can't just upload an image as an attachment in a pm.
To answer the question, as Vulc said, upload the flat image on any image hosting site and send the link in a PM.
