Hi Robert,
The image was pretty small anyway, so there isn't that much difference between the thumbnail and the full image. I was going to try and reimage Dan's smoker with the MOC but it broke down unfortunately. It's worth remembering that to date no one has found gases coming from the ground on Mars, except for some ambiguous images on the south pole. So Dan could still have found the one and only example of this.
There is also a link between the smoker and the dark streaks in the image. They look as if some kind of smoker, or geyser might have created them as well, they are on similar hills next to the smoker and point in the same direction. So potentially the smoker could be relevant to other streaks like these on Mars. For example a pocket of ice might start to sublimate, outgas and send up some fine dust which starts a small avalanche creating the streak.
