Phew! That tested my memory -
The earth/moon was an APOD, with the image from the Mars Global Surveyor:

The other two images must have come from MGS archives, I think. Too hard to find now...
There is a similar image at ESA, from the Mars Express. The link is:

Hope this is OK. I downloaded the pics quite a while ago.
Cheers -
