Try feh for a more configurable viewer.

Note that you can run sxiv from Emacs with the 'sxiv' MELPA
package, at least I think that's what it does. I guess not all
Emacs users share your aversion to "external commands" ...

It isn't as good, that's the issue. No idea why on cannot read
a non-regular file from Elisp, but head(1) and pwgen(1) can do
it from C, and Emacs is written in C as well, so maybe it can
be done as a C built-in (Lisp primitive) or, as said, in
a C dynamic module ...
