I found one of moodflow's earlier image displacement links in the forum. This link should take you right to an example he made (with tgd files).

My search criteria was image displacements and I used moodflow in the last filtering input. This will bring up many threads he has posted on using image maps for displacement; hence he reply of "what" as he thought, "doesn't anyone read around here?"

I think Moodflow has come up with something new, so I'm interested in hearing his new findings.
So this is Disney World.  Can we live here?

Could be. I am curious what he is using for the displacement image also. ???

Hey guys, sorry for not responding.  I keep getting caught up in life's web of responsibility!

For image based displacement, you have to carefully extract or create the displacement from the image.  I used photoshop to do this, and it was very time consuming.  The displacement usually does NOT really match the colors/shading on the image, so its very tricky to get just right, and even then, its still not 100% accurate.  Additionally, you are limited by the pixel level of the image, so up close shots usually won't work well. 

In this image, I got pretty lucky.  I wish I had more time to do a full write up on this, but it would be pages and pages worth of stuff.

I am still curious as to the images, before photoshop and after. Using a photograph could be a quick way to get a really good landscape.

I think that using P.Shop is only to get a greyscale image from the original one and using it to create a image bump ...

I did one day found this example in planetside forum ; that use an image map shader as a texture for the landscape, I've made a little modification to see what it gives with fakestone ,ehh(that's my cloud) the result ?
See it :
