Please attach your screenshots to your question directly. I've given you sufficient karma for that.

It's not entirely clear to me what isn't working for you.

For screenshots to appear, you need to click the image button (next to the button with 101010 on it) and then follow the prompts.

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"/>

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"/>

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".
