You just to it on a single tag.
<remap from="rgb/image" to="/camera/rgb/image_raw"/>
A more complete example below. Note the "node" tag, because you're launching a node and remapping it's topics.
<node name="rtabmap" pkg="rtabmap_ros" type="rtabmap" output="screen">
<remap from="scan" to="/scan"/>
<remap from="camera" to="/camera1"/>
</node>
Doing it with an include file like below WILL NOT work i don't think (someone correct me if im wrong).
<include if="$(arg kinect)" file="$(find openni_launch)/launch/openni.launch">
<remap from="camera" to="/camera1"/>
</include>
Also, note that "scan" is different from "/scan".
Having only "scan" without the "/" will place the topic under whatever namespace your node is running.
Take the rtabmap example above. Putting to="/scan" will use the topic "/scan". Using to="scan" will put it under "/rtabmap/scan".
Please attach your screenshots to your question directly. I've given you sufficient karma for that.
