Ok before you say anything, consider this, I am using other peoples brushes only because I have lost my own. Also, this tutorial is meant to for people who want it simple and easy. So don't go blaming me for it not being "good enough" or some other lame reason someone seems to point at me. So without furthur ado:

First off open up PhotoShop (CS?) and create a transparent document of a width of 450 and a height of 120

First layer: Filter -> Render -> Clouds


Create a new layer, download this brush. and load it.

With your newly created layer, brush evenly with black using the Crown__s_Fractals brush


Create a new layer, download this brush. and load it.

With your newly created layer, brush evenly with white using the RoD_Inc___Render_Brushes brush. Set the layer mode to Soft Light.


Create a new layer and take this picture (Tutorial Link Here)

and add it to the layer and set the mode to Soft Light

It should now look like this:


Now click this button and click Colour Balance

Mess around with the settings, I used

Midtones: 0 +60 0
Shadows: 0 +27 -31
Highlights: 0 +19 +55

Now your done your grunge-like background! This is my final result:
