So you actually mean that you should apply a general compression
without any consideration of the image subject . That would mean you
have to set it very low and the download sizes will be huge for a
2000x2000 cubefaces.
I done some tests and you will have 6-7 mb per fullscreen panorama
at a 60% (Mac) compression.
