newbie question

I'm new to Octave, but managed to get it successfully installed and tested it successfully on some plots and small matrix manipulations.
I'd like to use 16 bit tif or txt images as matrices and manipulate them in Octave.  I'm not sure how to load an image as a matrix in Octave and assign it to a letter name for manipulation.
I've ordered John Eaton's book but it won't arrive for a while.... thought I'd ask here so I could get started.  I've looked at the html version of the book on the web, but it doesn't seem to directly answer the question.
