Thassright.
libpng16 neither in Slackware package nor in source to be found.
After due thought, and taking into consideration being able to live without
png in ImageMagick, decided on a plan of attack, which involved proceeding up the list of
libpng16 RPMs at
pkgs.org, doing a higher version whenever there were a few moments to spare.
Next RPM up

Struck paydirt!
Now unsure whether due to hitting upon compatible version, or due to
libpng of same version being provided as well in package, as previous RPM did not provide such.
