Thank you, Marco and Andrey.

I'm relieved and I've decided not to care the info.


But, I've dropped another example. Just reporting it:

$ pngcheck a.png b.png > ab.log; echo ----; cat ab.log; echo ----
----
zlib warning:  different version (expected 1.2.8, using 1.2.11)

OK: a.png (1000x1000, 16-bit grayscale+alpha, non-interlaced, 96.1%).
OK: b.png (1000x1000, 16-bit grayscale+alpha, non-interlaced, 97.0%).

No errors were detected in 2 of the 2 files tested.

Regards,
