Two ways.

First, layer group and scale dependencies:

  • create N separate layers, associate each one with a different set of activation scales in their style (take the raster style, copy, add min and max scale denominators). See also the documentation
  • make each layer "non advertised"
  • lump them all toghether in a layer group (or if you are on 2.11, skip the non advertised bit above and just create a "opaque container" layer group)

Second approach, use image pyramid:

  • Download and install the pyramid extension
  • Put each file in a different folder, naming them 0, 1, 2, 3, ....
  • Point the image pyramid to the parent folder, it will automatically figure out the image resolutions and setup scale switches based on that
  • If that does not satisfy you, go and tweak the pyramid property file in the parent folder
