you need to sample the pixels in the image sampler... so plug in a range component to a PointXYZ (into the X and Y inputs for example, z i not useful in this case) and cross reference the pointXYZ...plug THAT into the image sampler...the default output is RGB values, but you can change the filter (by right clicking on the image sampler) to give you other data sets...
