What is the best way to compare multiple images and point out differences?

I have been working on a project in which I have number of images(webpage images to be precise) which are almost similar. I need to compare those images and find out the differences and generate the report for the same. Please help me out by guiding with the best way for pointing it out. Can someone please suggest me some books or tutorial to learn Matlab as quickly as possible.

Convert those images to Binary, then apply

use 'corr2' function in matlab, it will take very less time for comparing images.

use Matlab user guide for basic and for image processing use "Digital Image Processing with MATLAB" by Gonzalez text book.
