Rename images to folder name batch file

This is the tree in the folders:
\WaterMark04292015\4B-MiniMatic-2-1mm-adj-AR21040-HTML\Images\4B-MiniMatic-2-1mm-adj-AR21040-HTML\Lv1

In this tree under the LV1 folder  there are images named: img01.jpg/img02.jpg/img03.jpg etc. upto img20.jpg

I want to rename the images to: 4B-MiniMatic-2-1mm-adj-AR21040_01.jpg uptil _20.jpg

I attached a listing of the folders within the main folder. Can a batch file be used to do this or is there a third party app I can use?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

- Make a .bat file of this code.
- Code makes a .log in your TEMP folder
- Be sure to do on a test folder first!
@echo off
