Found it @ NASA after all.
Although not that exact photo, there is a similar one at the NASA site. Some of the ones there are a bit too digitized for my taste. :{

Here's another view of Saturn 'we' don't get to see every day:

The Cassini division looks brightest due to the faint materials within it that we normally don't get to see from Earth.
