Specular Details On texture Not showing

I made a Texture On gimp for the Diffuse and Specular im start giving details to the specular texture but i doesnt show on render did i do something Wrong on making the Texture or am I missing an Important Step?

Mesh and the Specular with Details:


On the materials Properties i already Set the Specular intensity 0 and Hardness as Default which is 50 and also i Unchecked the Color setting and Turned on the Specular Intensity on the texture

Did i make the specular base to bright or something?Or is it some Important steps that i missed? Please help me solve it
