for more information.
Comment 1 Raphaël Quinet 2002-04-18 18:11:51 UTC 
There have been many requests on the gimp-developer list, on the
gimp-user list and in the comp.graphics.apps.gimp newsgroup for MNG
support in the GIMP.  But apparently nobody had submitted this to
Bugzilla until now.  Since JNG is part of the MNG specification, I
will change the subject of this report and include both.

Now the only thing that we need is a volunteer who can write a
plug-in that reads and writes MNG and JNG files...
Comment 2 Sven Neumann 2002-09-03 11:28:07 UTC 
If I ever finish b2mng (part of blinkentools-2) w/o loosing the last
bits of my mind, I might even consider to start writing a MNG plug-in.
Comment 3 Frank Richter 2003-02-08 23:56:27 UTC 
I have created a plugin for loading/writing JNG images. It can be
found in the registry.
Comment 4 Helge Hielscher 2003-02-10 05:12:15 UTC 
There is a beta of a MNG Plugin at http://www.mukund.org/gimp/mng/

Changes at the request of Dave Neary on the developer mailing list.  
I am changing many of the bugzilla reports that have not specified a target
milestone to Future milestone.  Hope that is acceptable.
Comment 7 Tino Schwarze 2003-07-24 08:59:07 UTC 
The MNG plugin also saves JNGs.
Comment 8 Jakub Steiner 2003-07-24 09:19:24 UTC 
To 'support' mng/jng I'd say the filter needs to be able to import as
well as export. Marking Future

Comment 11 Alan Horkan 2005-02-09 15:47:07 UTC 
(This has probably already been said elsewhere but I wanted to make sure to
include it here too.)
Even very basic support for this would be very useful, being able to import as
much as the GIMP exports would be excellent.  
Aside from PSD there is no standard layered image file format suitable for
sharing files with users of other programs and MNG seems like it might be the
best bet for users who dont want to support Adobe but still want to preserve
their layered images.
Comment 12 Martin Nordholts 2010-06-29 18:42:19 UTC 
Let's improve OpenRaster support instead.
