I believe it does. I probably messed this up for you a while back when
I changed the node name logic in the driver. For compatibility, I
publish camera/image_raw relative to the driver node name.

By contrast, the wge100 driver publishes image_raw relative to a node
handles set to:

    camera_node_handle_(nh.resolveName("camera")),
    camera_node_handle_alt_(nh.resolveName("camera_alternate")),

This may make a difference in how remapping works. I am still trying
to completely understand this stuff.
