If possible, the first images in each set will be true-color, as you would see them with your own eyes. Most images will either be true-color or monochrome (black and white), unless stated otherwise. Many images can be vastly enlarged by clicking on them and choosing a larger size from the Flickr page. Downloading them may allow even larger sizes.
It appears there's a limit to the size of diaries, so this first part of the tour ends about 3/4 of the way through the Saturn system (which is quite extensive).
You might be tempted to think Mercury is very similar to the Moon, but compare and contrast them, and think about what the differences might mean.

This is a perspective mosaic of Venera images put together by Don P. Mitchell, which shows roughly what a human being would see on the surface of Venus:
Can you spot Earth in this Voyager 2 image taken beyond Pluto?
There are only two NEOs that have clear, interesting, photographic images at the moment. There are tons more that either have blurry, mundane images, computer-generated images based on radar data, or just specks on a starfield.
- 25143 Itokawa
- 433 Eros
(No, this is not a joke - an asteroid named Eros looks like this...)

Some of these images are marginal, because we have not yet sent dedicated probes to Main Belt objects and have to rely on the Hubble Space Telescope and other observatories in most cases. Superior images were obtained only by probes destined for outer planets passing through the Main Belt. In the case of comets, they may have been imaged from a point closer than the Main Belt, but I include them arbitrarily because their orbits are usually too eccentric to categorize regionally. There are tens of thousands of cataloged objects for which there are no clear, close-up images.
- 243 Ida (and its satellite Dactyl, in first image)

This is the largest asteroid in the solar system (hence its being spherical), and possibly destined for human settlement. It's thus a scandal that we still don't have any decent images of it (though we're sending the Dawn probe, which will arrive in 2015). This is from Hubble:
- 4 Vesta
- Comet Borrelly
- Comet Wild 2 (pronounced "Vilt" 2)
- Comet Tempel 1
Planned collision of Deep Impact interceptor probe with Comet Tempel 1:
- Halley's Comet

Jupiter has dozens of moons, but we only have decent images of the Galilean satellites and a couple of the small, captured asteroid variety.

Size comparison of Ganymede, Callisto, Io, and Europa:
As with Jupiter, most moons of Saturn are just asteroid rubble, so most have no images. However, there are many more that do have images thanks to the Cassini probe.
Notice that this moon causes waves in the rings to either side of it due to gravitational perturbation:
The shadow of F Ring lies across it:
