Surely the simplest way to understand is just to run the code?!

Assuming that image is an NxN array, this command plots a single green line that
  • along the x-axis, goes from 1 to N
  • along the y-axis, goes along the mean value of the 1st through Nth rows
See details in the documentation for plot.
(Also, I assume you mean that "image" and "Image" are the same variable, and just did a typo in capitalization.)

For the size command, it is specifying the dimension of the array that want the size of. In this case, you are specifying that you want the size in the first dimension, which is along the columns.
Similarly, for the mean command, it is specifying that you want the mean along dimension 2.
