I keep seeing people using these in the gallery, so what do they stand for? Is it something like High Definition Rendered Image? Thanks :)

It stands for High Dynamic Range Imaging. It can't be done in Bryce, just simulated. In real HDRI, the surrounding environment is made up of bitmaps that have unlimited brightness for each of their pixels. So instead of having 0..255 like in a BMP, you could have 300, or 3000, or 300000000! The light is then used to light the whole scene, and also provide reflections.

In Bryce it's usually a sphere with a real world pic applied as a texture and surround your scene with it, using high ambience and diffusion. Objects in your scene need some reflection, there sphere will provide the "light" to light your scene. Search the forum for some examples on how it's done.
