• For pngnq: you have supplied a JPG file while the toolset only works with PNG files as the input.
• For pngcrush: malformed or missing argument:
  Remove the -max from pngcrush parameters in the main script, as that expects a parameter (default 8192) - for reference, this is the max size of IHDR.
  Also recommend removing -m 0 as that otherwise will throw warnings about ignoring invalid method (valid values are 1-150 in latest pngcrush).
  Errors after that are because of the pngcrush failure and should disappear when you fix this.
• For pngout, the install script will fail to install that as the link is now outdated and no longer valid. Download and manually install this version, latest as of today: https://www.jonof.id.au/files/kenutils/pngout-20150319-linux.tar.gz
