\includegraphics: File not found

Question

I am trying to insert an image with the graphicx package using LuaLaTeX. I receive an error that the file cannot be found. I get this whether I use the \graphicspath argument or include the complete path in \includegraphics. After reading all similar discussions I could find, I have arrived at this code:

    \documentclass[12pt]{article}
    \usepackage{graphicx}
    \graphicspath{{Figures/}}
    \usepackage{fontspec}
    \setmainfont{Century Gothic}

    \begin{document}
    \begin{figure}
    \centering
    \includegraphics{ACTB Normalized.png}
    \end{figure}
    \end{document}

The error I receive is:

LaTeX Warning: File `ACTB Normalized.png' not found on input line 10.

! Package luatex.def Error: File `ACTB Normalized.png' not found: using draft setting.

See the luatex.def package documentation for explanation. Type H for immediate help. ...

l.10 \includegraphics{ACTB Normalized.png}

I have also tried other image file formats including .jpg, .pdf, and .eps. Any insights on this issue would be greatly appreciated. Thank you!

Answer 1

Turned out to be a very simple solution. Apparently it didn't like the space in the filename of my graphic. Removing spaces or using grffile package solves the problem. Thank you for your comments!

Answer 2

Do not use accented characters or space in the file path
