What program did you use to determine this? I'm looking at one of our
jpgs in a text editor, and while I see the string "Exif" near the top, I
don't see any jfif-like string. GIMP reports 72x72 ppi, but I don't
know whether that's exif or jfif.

Is there a work-around? Like using some image editor to produce a jpg
file with jfif and exif headers that agree on the resolution (and I
suppose have the correct one :-)), or maybe converting from jpg to some
other format? I suppose I could create a PDF using pdflatex, and import
that into my xetex file instead of the original jpg. But before I try
all these things, it would be nice to know if someone else has found a
work-around...
