Hoping somebody can point me in the right direction.  There are
actually two related problems I'm having.  I would like to have a
slick, efficient, lightweight image viewer for single images stored on
a hard drive.  Zooming and panning would be great.

The second part of that is more complex...

I'd like to have the ability to handle geojpeg2000 images also, and
display coordinates as you move your mouse.

so...my questions to the group are...

1) does anybody know of a lightweight viewer?
2) has anyone worked with a js solution to handling geojpeg2000 files?
