I wonder what Irfanview does to handle this as it's viewable in that...or the older version of libtiff?

Does Irfanview use libtiff?

Also, I tried to checkout that old version of libtiff and build it inside an ubuntu docker image, but it's getting errors when I try to make it (after I got past having to ln -s /bin/sed /usr/bin/sed):

I suggest that you look for a tarball in the libtiff 'old' directory on the ftp site since its build configuration should be complete. This may or may not resolve your sed issue.

/development/libtiff# make
Making all in port
make[1]: Entering directory '/development/libtiff/port' /bin/bash ../libtool  --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I. -I../libtiff     -g -O2 -Wall -W -MT dummy.lo -MD -MP -MF .deps/dummy.Tpo -c -o dummy.lo dummy.c
libtool: Version mismatch error.  This is libtool 2.1a, but the

libtool: and run autoconf again.

Makefile:507: recipe for target 'all-recursive' failed
make: *** [all-recursive] Error 1

See what the autogen.sh script for the old, or the current libtiff uses. If possible run autogen.sh. This is what is in the current autogen.sh:

   #!/bin/sh
   set -x
   libtoolize --force --copy
   aclocal -I ./m4
   autoheader
   automake --foreign --add-missing --copy
   autoconf

Is there a prebuilt archive of older libtiff libraries or one I can apt-get install explicitly to see if it'll work?

Expecting to install this old library via apt-get is a pipe dream. :-)
