gives no problems here, e. g. in plain pdfetex 1.11b this works without
any warning or error:

\pdfximage{finger.jpg}
\setbox0=3D\hbox{\pdfrefximage\pdflastximage}
\showthe\wd0
\showthe\ht0
\showthe\dp0
\box0
\bye

gives 1284.8pt/963.6pt/0.0pt

And it looked like your error came right out of pdfetex. This Exif-JPEG
format is _tolerated_ by pdf(e)tex since 1.10a, and no change in the
code since then. Do you happen to use an older pdfetex version? But why
is Hans' texexec giving problems?

=2E..which has most likely removed the Exif header.
