It depends on the platform.  WebKit uses the Core Graphics ("CG") framework with Apple's Safari web browser on Mac OS X and Windows, not the decoders in the WebCore/platform/image-decoders directory.  Thus Safari does support the JPEG2000 format, although there is currently one bug open on bugs.webkit.org about it:

JPEG 2000 images display intermittently

I'm not sure about other platforms.  I'd guess that if there isn't a decoder for JPEG2000 in WebCore/platform/image-decoders then it's not currently supported.
