When used with an image, the third output of the size() function represents how many color channels there are: 1 for a gray scale image and 3 for an RGB image. There are some watchouts if you only accept two size() outputs and you actually really have an RGB image and not a gray scale image. See the link below.
See Steve's blog discussion about this: Too much information about the size function.
