Here's the minimal PIL version:

	import sys, Image
	for f in sys.argv[1:]:
	    print f, Image.open(f).size

When you open a file in PIL, it only parses the file header.  The
raster data is not read until you try to do something with it, so the
above is quite fast, independent of the image size.

See the pilfile.py script for a somewhat more polished variant.

BTW, you don't have to link with the PIL C extension to use the above
feature...
