Recently I've been trying to make some PDFs smaller by using better
compression of JPEG pictures.

I was happy to see that \externalfigure cheerfully accepts .jp2 (JPEG 2000)
files.  However, my understanding (and I could well be wrong, but I've seen
it multiple places) is that JPEG 2000 *Part 2* files should have extension
.jpx, not .jp2.

By default, ConTeXt does not recognize .jpx.  But if I rename a .jpx file
to have a .jp2 extension, then ConTeXt properly processes the file and I
see the picture in the PDF.

Q: are there any plans to make ConTeXt recognize the .jpx extension?
    If not, can anyone suggest some ConTeXt code which allows me to tell
    ConTeXt to process a .jpx file as a .jp2 file?


Adding

    \definegraphictypesynonym [jpx] [jp2]

at the begin of your document should do the trick.
