Is there a way to adjust the scale and position of my image textures?
The dimensions of my image are 1024px x 1024px.
let textureMap = THREE.ImageUtils.loadTexture( 'texture.png' );

Take a look at the texture documentation:
.repeat - Specifies how many times the texture is repeated across the surface, both horizontally (U) and vertically (V).
.offset - Determines the offset of a single repetition of the texture from the starting point, in both U and V directions. Typically ranges from 0.0 to 1.0.
.wrapS - The default wrapping option is THREE.ClampToEdgeWrapping, where the edges are clamped to the outer texels. The other choices are THREE.RepeatWrapping and THREE.MirroredRepeatWrapping.
.wrapT - Similar to wrapS, but for the V direction.
NOTE: Image tiling in textures only works properly if the dimensions are powers of two (2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, ...) in terms of pixels. The dimensions don't have to be equal, but each must be a power of two. This limitation is due to WebGL, not Three.js.
Scale examples:
// scale x2 horizontally
texture.repeat.set(0.5, 1);
// scale x2 vertically
texture.repeat.set(1, 0.5);
// scale x2 proportionally
texture.repeat.set(0.5, 0.5);
To adjust the position, use texture.offset.set(u, v); where u and v represent percentages (e.g. 0.67).
While there isn't a specific scale method, you can achieve similar results using the arguments in .repeat():
