@REM - GetImageURLs.BAT (23 Jun 2024 // 24 Jun 2024): Get Image URLs from HTML Download
@ECHO OFF

 ::: This script will return the image URLs from an HTML page.  
 ::: I performed rudimentary testing only.  It relies on a 3rd party utility:
 ::: READABLE.EXE (https://www.majorgeeks.com/files/details/readable.html)
 ::: 
 ::: I tested https://www.newgrounds.com/art/view/thewendigo/tree and
 ::: https://www.newgrounds.com/art/view/missandydandy/punch-punch-forever
 :::
 ::: Rather than supply multiple files, I just had the script generate the 
 ::: search/replace config file used by READABLE.   
 ::: 
 ::: Once the files have been parsed, I download them to the %#SAVEDIR% folder.
