I made a .tex file on windows xp. and generated a PDF.
But when i switched to Mac os and use Texshop to generate a PDF, it doesnt work!
it said this:
LaTeX Warning: File `q1.jpg' not found on input line 70.
!pdfTeX error: /usr/texbin/pdflatex (file q1.jpg): cannot find image file
==> Fatal error occurred, no output PDF file produced!
Why does this happen?
