------------------------------------------------------------------------

I have simply about 40 pictures in the org file, and only 18 pictures
are showing regularly, while other pictures show on the side of the PDF
file, LaTeX output, cut and not visible. I have tried many things, but
could not make more than 18 pictures to display properly.

I am using following format to display pictures

#+CAPTION: Title of picture
#+NAME: fig:pic001
[[/some/picture.jpg]]
