Snapshots only in JPEG ? #109

Are the snapshots images always in Jpeg format? Because when I try the type=png in the link for the snapshots I keep receiving a jpeg image.

Looks like this is already implemented here, but there is no way to configure the node to actually output the snapshot in png format. It only works while streaming.

I'm looking for this feature as well, I'd like to get a "lossless" snapshot (a stream is not necessary), especially because I'm interested in depth pictures where any lossy compression will basically destroy the data.
