Go to your styles dialog > In model (the little house icon) > Edit > Watermark settings (the little icon with the "OK" sign). There you can ad a background image with a bunch of settings after you start adding it (see screenshot)

Then make sure that in your background settings ground is turned on (it should be by default in the 3D templates) otherwise the sky image will see through the ground:
