This is how misunderstandings and flame wars start when people like you don't read posts properly and note who posted them. Learn to use this BBS properly first before making sweeping statements (referring to me) like, "He created that face on mars with some graphics software, I could do the same."
Now go find out more about the <a href="[www-pdsimage.wr.usgs.gov] Data System</a> sponsored by NASA at their FAQ page; then you will understand how that particular picture came about. In fact I'll quote you a bit so others can see:
Q: What is PDS?
A: PDS stands for Planetary Data System. The Planetary Data System archives and distributes digital data from past and present NASA planetary missions, astronomical observations, and laboratory measurements. The PDS is sponsored by NASA's Office of Space Science to ensure the long-term usability of data, to stimulate research, to facilitate data access, and to support correlative analysis. The part of PDS responsible for the PDS Mars Explorer for the Armchair Astronaut is the Imaging Node.
Now apologize David and calm down.
