for the pics, I think you just repeat the process you used for that pic. I also believe you have to wait until you reach 50 posts and get a "registered +" status. I have been using an online picture hosting service then using the link to those photos within the message by hitting the picture Icon in the message edit dialog box.

From the picture, it appears you have your burn issue solved. I was going to suggest you may have over nuted them to early but they look good to me.

Best of luck!
