How much of the Poser Gallery is pure Poser?

I ask this as someone coming new to Poser. So far my experience of Poser, is that it is a fantastic human anatomy (+other creatures) manipulation package, but for the life of me I can't seem to find where in the Poser software there is anything that can create skies, greecian pillars, trees etc.

Am I naive to think at first all these brillint images came from Poser?

If I recall there is something somewhere on this site that states that the galleries contain images solely produced by the named software applications.

Isn't this a somewhat misleading?

Shouldn't the images either be cross posted to other galleries, or at least mention ALL the software that is used to create them. It's this kind of information a real beginner needs!
