Pic of my Mchannel and another pic of the covered riser hopefully in the feed.

Hi I just posted a pick of the the heat riser cover and mentioned the burn chamber and the wood pellets. I wanted to include a pic of the fire and how the Mchannel works. (thats Mikael Channel if you were wondering) I also noticed that my first pic came up as something that needed to be downloaded how do you get the pic in the post and is there a prefered format. jpeg over pdf?
