As I recall, ImageJ doesn't yet (as of 1.35a?) support 16-bit PNG
format.  I was looking into this because I'm serving up 16-bit (TIFF)
images over the Web, too.  (I don't use ImagePlus(url).show() because I
need to send a cookie in the HTTP request; there may be a way to do
this with ImagePlus(url), but I don't know how.)

How large are your images?  Is the compression you get with PNG
critical, or are you using a client that can't deal with TIFFs?
