I thought I'd add this link:

The collection of NASA images, some are rather good. In addition, if you have a pair of stereoscopic glasses (those, usually card, ones with one red and one green filters over the eyes), there are a number of stereoscopic pictures too.
Many of these are less specifically stunning as the ones in the link from the OP, but only in that, possibly, they look slightly less naturally arty.
Some ones that I've found that are rather good are, from Mars missions:
Mars' Moon `Deimos':

Mars' Moon `Phobos':
http://www.nasa.gov/mission_pages/MR.../pia10369.html
Phobos and Deimos are actually pretty pathetic, as moons go, tiny unshapely things... tsk...
Mars' North Pole:

And us! As seen from Mars orbit:

From the Cassini-Huygens mission:
An absolutely stunning picture of Enceladus, one of the prime candidates for potentially hosting life:

another of Enceladus:

Enceladus seems likely to have oceans of liquid water beneath its surface. It has a number of geysers(/cryovolcanoes I'm not sure what exactly geologists have determined them to be) spraying out a mixture of chemicals including water vapour, nitrogen, CO2 and several organic compounds, these geysers(/cryovolcanoes) are thought to be the source of Saturns E-Ring, the furthest out band of Saturns system of rings. Between the likely presence of water, the volcanism to provide heat, and likely detection of organic compounds, I'm fairly hopeful for the potentially of actually finding life there, crazy space-bacteria of some sort. Or some sort of giant space squid, living deep in the sub-surface oceans...

We can but dream....

Before looking at these last pictures, it's important to start humming the `Imperial March' from Star Wars... `That's no moon!' etc...

Saturn's Moon Mimas, of course, with its likeness to a certain giant space station...
There are many more as well, I haven't included anything from Hubble, which obviously will have loads of amazing pictures.
