Infrared is radiation just to the red side of the visible spectrum. Generally, we think of infrared radiation as heat (even though that comes with some asterix as well, but that goes too far). <br /><br />So, think of these images as colored heat maps. Kinda like the green images you remember from the night vision stuff in the Iraq war, but infinitely more fancy.
