Thank you very much for the help. That makes sense, as I remember reading about
the image placement, but I didn't think it mattered. My use is very simple, I
occasionally need to covert images into to PDF's and this makes it easier than
going online. So I figured it was okay to leave that out. I need to go back and
read the manual some more.
It's a CLI program, it takes a few different arguments and when it's done it
just returns to the shell. That's why I have the exit() where I do. Is there a
better/safer way to exit the program?
