> I can reproduce your overlap. I had something like this happen to me once. It was a corrupt jpg. So I pushed your tombe.jpg through GraphicConverter (Mac OS X) making it 1 pixel narrower and it now scales properly and does not overlap the text. I think I'm using pdflatex too.

Further testing of my photos: many of my photos have a 300dpi resolution. Those with 72dpi work fine with xelatex and pdftex. Photos with 300dpi resolution scale only in pdftex.
