It is basically this:
-Press F5 (F6, F7 and F8, work the same way
) to do the screenshot. (I believe that you know how to position the camera in the way you want, in this case to focus on the head. Otherwise, ask about it).
-At this moment the screenshot will be sent to the Toribash folder on your computer (Computer> Local Disk C > Games > Toribash > screenshots)
-Then you need to upload your screenshot with a site that hosts images (ImageShack
are the most recommended and used)
-When you uploaded it, the "URL" of your image will be provided, so you only need to copy and paste it. (Using the code [IMG]URL of your image here[/IMG])
