Welcome to the Group Damon, if you need anything feel free to contact myself or Jace or any other member of Management and we will be happy to assist as much as possible. I find your pic a bit odd, and a touch disturbing but as far as I know it is not in use so feel free.
For posting pics into threads you should be able to use the 'img' button in the bar just above the text box. You will need the image URL for this to work. As I recall I had some trouble with this at some point so I had to edit in HTML. Its going to be easier to use pics that are uploaded to this site though, keep that in mind.
If I can help more let me know.
