Are there any plans to include MNG support? FF3 doesn't support MNG now.

No, get further information from bug 18574 please.

Oh, just to mention it: Firefox 3 and Opera support the backward-compatible APNG format, see https://wiki.mozilla.org/APNG_Specification

But why the JNP has not been?
Oups : JNG (JPEG Network Graphics)
Agreed on the JNG. Very sad.
APNG is pretty much useless.
Virtually everything it does can be done with a bit of javascript and CSS in a much more cross-browser format, and, yeah no JNG.

MNG covered an excellent niche area between things like flash/canvas/webgl and basic formats like jpeg/png.

And there is still no useful replacement for JNG.  I suppose I could implement one using <canvas>, a mask jpeg of the alpha channel and a jpeg of the RGB.
Besides Flash, there is no JPEG format with transparencies. Suddenly, I use Flash. Yet there is JNG or JP2, but neither is supported.
Hm. You can do translucent jpeg with Flash?
I was trying to think of doing it with <canvas> - If I compress both a masking greyscale JPEG and an RGB JPEG, seems results could be some odd artifact side effects. I'll have to give that a shot, see what happens.
Also I guess less efficient.
> Hm. You can do translucent jpeg with Flash?

Yes, the JPG compression on a PNG is permitted with Adobe Flash.
PNG : 75 KB vs. SWF : 15 KB
That's sad, and even more damning of the politics that got JNG/MNG killed.
Still, I think I'd prefer to use <canvas> - avoids shoving a plugin in the page, much more flexible.
Might even be possible to get it working w/ ex-canvas...
