Some further probing showed that it worked by me as well! But with one
LaTex related restriction that I missed. The included filename must *not*
include more than one period! In my original file I had part of the
experiment conditions encoded in the name, e..g. lc-p0.5.jpg . This works
fine in HTML but fails in LaTeX.

Running pdflatex on the tex file yields:

! LaTeX Error: Unknown graphics extension: .5.jpg .

The problem has nothing to do with the org exporting, and is a LaTeX
limitation that I can live with. Case closed. :-)
