I had previously raised a question regarding ListContourPlot3D but got no response. For some work i need contours (base on discrete data) in combination with Image3D, which i had working previously.

No to make this work i need to jump some hoops to make it work. While looking for alternatives i also looked at ArrayPlot3D where i found some strange behavior also.

I am aware of all the different axes conventions Mathematica uses for Images, Graphics, Arrays, Matrixes etc. (would be nice to have a nice guide on this topic since its getting confusing), but based on my experience here there are some internal size and dimension flips for these functions that are unintended.
