Looking at the texture in the picture, in addition to the curves suggestion above, I would apply the same texture as a specular map and a bump map. Here's an example set up with the specular map:

I didn't have a way to make a normal map on this computer, but that would finalize the effect, with some good lighting effects like your reference image.

Yes I forgot to mention displacement. Thanks – Nils Eisen May 22 '16 at 05:47
Note that this setup is for Blender Internal render and not for Cycles, as stated on the question. – May 22 '16 at 05:53
The only difference is you need to use a "material output" node for cycles, and tweak the curves a bit. – Jordan Davis May 22 '16 at 06:00

For cycles. Use the texture to control how two different shaders mix:

(the color ramp is just to control the the intensity of the mix, but curves or a color bright/contrast node would work as well)

A different option is to use the image to control the color on a single shader:

Or use the image to control the mix and create some displacement.

Or additionally use it as a bump map:

Thx! But for the third one, how can I add the brownish spots? – Jml19 May 22 '16 at 09:08
And, how can I add the textures that brown spots and the glossy effect? – Jml19 May 22 '16 at 11:18
You can add more textures and combine more shaders. Please go through the related links suggested on previous comment. – May 22 '16 at 15:26

You can use color curves in the node editor to change the color if you are using cycles. This can be found under the color menu. If this is meant for blender internal or BGE you should be able to edit the colors in the texture menu. I added some images to show.
