-* +*.jpg limit the mirror to just jpg's on that page.  There are no jpg's on
that page so you get nothing.

The science wallpapers are located on wallpapers/science-space
So you need to add +*wallpapers*

The actual science wallpapers are located on
<http://science.nationalgeographic.com/science/enlarge/neptune.html>

So you need to add external links=3 and +*.html
