This Style?

How do you do something like that?

 

I believe it's just grungy brushes slapped on, along with some gradient maps and/or color balance layers.
The diagonal lines would be something like this I think.

Also, moved this to the correct section.

 

There is a tut for something similar to this, but i can't find it at the moment. it's floating around the web though. anyways, the most i can recall is like above said, its grunge brushes with some color maps...and probably the border is

something like that.

 

Oh yes, totally forgot about the border.
Thanks for adding it in DAC.

 

color effect was achieved by doing something like this http://www.trap17.com/index.php/make-multi...hop_t22167.html

 

It looks like they just used many different pictures and blended them together with layer masks.
