There will be room for three plus gear and one stove... wanted it big so the stove was a good distance from the walls. To post a pic just do the same as if you are making a post. You will see a button that says browse beside an empty box that say attatchments. Find your pic and click post...you pic has to be under 1000 KB (I think that was the size. The pics I take with my camera are to big so I have been using my cell phone and they will work.
