As Gilles said: detail images are here to show that size reduction hasn't
affected the image quality, or details loss.

So you don't need to have an exact "extract" of the image. The perspective
may be changed, etc.

Can you go further? For example: i made a detailed model for my scene, but
you don't see all of it, or there's a shadow masking some details, etc.
Can i make a "model show"/demo instead of having an image extract (you know,
several point of views for one lone object)?

Could that be interpreded as "show us how far you've gone into details by
sending us two detailed views in 1024*748 minimum"? This would be less
restrictive, and easier to understand (i still haven't understand what
those detailed views should be... not all povers have a high english
level!).
