Here is a few minutes of hack which would hopefully help someone else:
pngchunks logo.png
File size: 5967 byte(s)
Offset Chunk Size
8 IHDR 13
33 iCCP 2627
2672 IDAT 3271
5955 IEND 0
Useful to quickly find out if we can further strip unnecessary chunks from the PNG image. Or even as a warming up before you fire your favorite hex viewer/editor.
It's pure, stand-alone, self-contained C code (i.e. compile using gcc -o pngchunks pngchunks.c), available at the usual X2 repository, find it under graphics/pngchunks.

Hi,
What is the difference with the pngchunks of pngtools (http://www.stillhq.com/pngtools/) ? Usually available in any sane distro.
@Cyrille: The utilities inside pngtools are comprehensive, this one is just a quick hack.
