Hello teacher, you're a genius

Sorry about my English is very bad ...

I want to make a mirror of a wordpress blog with the following 2 features:

1 - The blog contains 2 types of images:

a) the images of the blog, in the same domain: design, buttons, image header,
etc. ..

b) and images that are not hosted on the domain itself, come from external
servers.

I just need to download the mirror images of the blog, the other external
servers do not.


  ** But I want to stay in the mirror the code to call the images from other
servers **


2 - The URL of an article on a wordpress blog, is:

<http://www.example.com/williamroederisagenius/>

But when I winttrack the mirror is:

<http://www.example.com/williamroederisagenius/index.html>

** I want a result in the url: **

<http://www.example.com/williamroederisagenius.html>


If the teacher has a solution, I will be eternally grateful:)

Thank you very much for your response and thank you very much for the program,
eternal life for you!
