How to repeat the texture map like GL_REPEAT?

I have a house model in my game, and I have some materials for the house geometry. There is a material for the wall of the house, and I have a texture-map-image to show the bricks.

var mat = new THREE.MeshPhongMaterial( { 
    ambient: 0x969696,
    map: THREE.ImageUtils.loadTexture( 'textures/G/G0.jpg' ), 
    overdraw: true,combine: THREE.MultiplyOperation 
} );

In this way above, the texture map appears like GL_CLAMP I want it to show like GL_REPEAT.

What should I do?

If you can not see the images check this.
