Zero: That pic of yours that reveals how they "lie" is intended as an illustration to compare the scenery of mars with that of earth. All the pics on the mentioned site is actually ripped from www.MarsAnomalyResearch.com which is an excellent site with tons of very interesting photos. And there it is clearly stated that the mentioned pic is from the Earth for earthly forrest.
MvX: Thats some bad example pics to "explain" - I'd rather see you explain these:
Huge nozzle shooting liquid spray:

Closeup:

Notice the tubes the liquid is shootin out from , coming out from a big strang sphere/dome below.. what the heck is this thing?
And what about this old skull?

Closeup:

And the classical shrubs/trees:

Or the forrest?:

And is this lakes with vegetation growing around them?

And the more or less known tubes twisting their way through the martian desert:

More "tubes":

And this strange stuff, kinda watery/jelly alike with something floating around:

Heres some more photos i grabbed from the raw images section of the rovers on NASAs server.
This are some closeups of something that look organic, like mushrooms:

They seem to be growing up from cracks in the surface:

And here is a satellite photo with two strange structures I have marked next to eachother.. The right one kinda looks like a dam to me, with a lake above it, and water flowing down below it heh. And the left "building" is placed by the shores of the "lake":

And here is a pic taken by one of the rovers again on the surface, some strange artifact laying in the sand. kinda looks like a statue:

Another satellite photo. Think this is the same stuff as the infamous "tubes":

And the structure in this satellite photo is very interesting:

This satellite photo looks like more lakes:
