libpng ICCP warnings

known incorrect sRGB profile

well it doesnt causes me problem and loads my png. but i want to know whats going on. also made a research but more than what it does why it exist people tells how to solve. and it doesnt even causes problems (thats what i see in my system might be problematic with other systems)

does anyone know what it is and why it exist?? some info would be very good a link is more than enough

thx in advance

It's because libpng 1.6 or newer does more checking of the pngs, and one or more of the png files used has an old sRGB profile. It's supposed to just be a warning.

Please read PNG file format specification:
http://www.libpng.org/pub/png/spec/1.2/PNG-Chunks.html

And iCCP chunk specification:
