Using wget to download a directory and all images it references?

Question

I want to download all pages in http:// www.server.com/directory1/ and not the rest of http:// www.server.com/

However, most pages in the directory I want have images, which are not stored in http:// www.server.com/directory1/ but in http:// images.server.com/

I don't want everything in the images directory, only the images necessary for the pages I want. Not that I could download the whole image directory if I wanted to; accessing its index is 403 Forbidden. The pages I want don't have addresses as regular as in the "page requisites" examples here: http://www.gnu.org/software/wget/manual/wget.html#Recursive-Retrieval-Options The directory structure is of variable depth, so I can't use a fixed-depth recursion, either.
