I would imagine that Nuke's postage stamps (if that's what you mean to use them 
for) are calculated from the image that a node produces in the same way across 
the board - so the node requests the image from upstream and applies it as the 
postage stamp.

It would be quite nice, though, for Read nodes that are pointing at EXRs (and 
any other format that supports preview images) to be able to read them...
