Hey i want to design the reader to read the animatied PNG's created using fireworks (having more than one layer and frames) , can anybody tel me where can i find the formats of these chunks.

I suggest using libpng and libmng. I am not 100% sure, if they can read Fireworks. PNG chunks are quite difficult to understand.

Hmm... I found from http://www.libpng.org/pub/png/src/pngcheck-2.3.0.CHANGELOG that pngcheck has support for mkBT and prVW. I am not even sure, what this is exactly, but I think that if pngcheck has support for mkBT, prVW maybe the latest versions of libpng also support it or if pngcheck has it, maybe you can check its sourcecode.
