Unfortuantely, identify is horribly slow, especially for JPEG 2000 images (thanks to a very slow libjasper).

So instead of using identify:
identify -format "%wx%h" image.jp2

Use exiftool instead:
exiftool -s -s -s -ImageSize image.jp2

exiftool is 62.5 times faster(!!!) than identify for finding image size on my dual 2.0Ghz Athlon.
