What's a good way of showing extremely high resolution images like this?

I did a few absolutely spectacular renders some years ago of a buddhabrot fractal, I don't remember the resolution but probably at least 100k x 100k, but after weeks of rendering I couldn't show it to anyone. I could only view it piecewise myself, as it didn't fit in RAM.

It's been a bit of a white whale for me.

I also have a high-res animated 4D rotation render that's half a dozen Gb, but can't be streamed online because compression algorithms absolutely massacre the details, and nobody wants to download files that big.

There's https://en.wikipedia.org/wiki/Deep_Zoom for example.

> A DZI has two parts: a DZI file (with either a .dzi or .xml extension) and a subdirectory of image folders. Each folder in the image subdirectory is labeled with its level of resolution. Higher numbers correspond to a higher resolution level;[6] inside each folder are the image tiles corresponding to that level of resolution, numbered consecutively in columns from top left to bottom right.

Yeah, something like that is what I've been looking for.
