Is there a way to download entire contents of a page 
without having to download unnecessary contents in its 
depth ?
For example: I want to download the homepage (and JUST the 
homepage) of www.cnn.com

I can easily specify to download depth zero and get the 
text. However, many of the pics on that page are of lower 
depths (Ex: <http://www.cnn.com/abc/123/pic.jpg>). 

Therefore, would I be able to JUST download that particular 
pic (mind you, some may be different - like www.cnn.net, 
www.money.cnn.com or what have you) without having to 
download things like <http://www.cnn.com/abc> and 
<http://www.cnn.com/abc/123> ???
Please keep in mind that these pics change every so often 
and therefore, I cannot just put in the URL as a rule and 
have it downloaded individually.
