Hello to the community.

I'm trying to get all the images from a site that follow this structure:

<http://www.example.com/download_example.php?file=*.jpg>

Where * is a wildcard that varies in size. All images are in *.jpg format. So
I'd like to scan that path and grab every jpg that meets the filter:

<http://www.example.com/download_example.php?file=example1.jpg>
<http://www.example.com/download_example.php?file=pleexam22.jpg>
<http://www.example.com/download_example.php?file=expleam002.jpg>
...etc

Is it possible? I've tried LOTS of options and it either start downloading the
whole site, or it downloads nothing but some html and jsp.
