I was asking for an apng, not just a static png. And the browser-teams... well, those staff that makes all those browsers. Firefox has native support for apng, but other browsers should have that too. People need to use apng to make a demand for that support, else nothing will happen.
People need to start using apng and leave gifs behind. There's so many benefits, but mostly because it's lossless. Yeah, Photoshop should be able to do this natively too, but there is no demand for that... We must demand native support for apng!
