You could probably use the urlwrite function to download the images or the entire Web page, but a much easier way would simply be to create a subdirectory for them, right-click on each image, choose ‘Save Image As’ in the pop-up menu (Firefox, but similar commands exist in IE and other browsers), and then download each ‘.png’ image to its subdirectory on your computer. There aren’t that many.

They’re ‘.png’ images, so the imread and image functions would likely work. You have significantly more options if you have the Image Processing Toolbox.

NOTE: If Image Analyst suggests a different approach to reading or displaying them, do what he says.
