Andromeda measure filter can collect pixel data over specified
paths or areas, and export data to files. Not mean and SD, but
the raw data you could derive them from.

25-30 might be a reasonable number of thumbnails to cram
on a cd label, but how would you choose them among the
200-300 images that fit on a CD?

try Andromeda ScatterLight. It produces realistic highlights based
on the actual image data rather than drawn stars.

Tectures dates from the byegone era when a CD full of data
was considered "too big" to copy to your hard drive, so it expects
to use textures directly from the CD. You can copy the bulk data
from the CD to the top level of any disk.
