identify does it in 1 second on a 6793x5000 image (97Mb pnm).
(pnm is a very basic image format)

But i bet it can be dome much, much faster depending on
image type, since the size can be in metadata. Ohh, yes.
The same image as above but in jpeg format:

time identify hugeimage.jpg
real    0m0.083s
user    0m0.064s
sys     0m0.009s

But i guess it can be even faster than that using the
right libs. And my suggestion is for the preperties
dialog - a single file, not file lists.
