No see that's why your going to have to get this custom as in the script you'll have to specify only images inside the post to be downloaded so stuff like avatars, logos, RSS icons, DDL Buttons, adverts etc won't be downloaded. This would be done by regex and something like:

<div id="post-00" clsss="post"> CHECK CONTENT HERE FOR IMAGES </div>

It's not to hard and you'd probably get it coded for $20-30
