Pioneer's Jovian Moons Images., Questions Options

[Decepticon]

I found it odd that most astronomy books that I read never mentioned that they where imaged.
Here are some images from the book.
http://history.nasa.gov/SP-349/ch6.htm (Figure 6-5)

1. What hemispheres where imaged by the Pioneer's?

2. Has anyone used current moons maps to create what Pioneer could of imaged if it had better imaging capabilities?

3. If Pioneer 11 imaged IO what area could have been seen? (I understand Pioneer experience radiation exposure and caused a failed imaging attempted?)

4. Any why does Ganymede look so odd in the above link?(Figure 6-5)
