How do I get images from a webpage within another webpage?

How do I get images from a webpage within another webpage without entering a dozen or so webpages from get specific urls?

Ex: http://www.example.com/PageA/1/2/3.jpg

http://www.example.com/PageB/1/2/3.jpg

Essentially, I would like to start that if highest order domain page and capture all the images from the subpages.
