I'm a recent newcomer to LaTex and while I've overcome most of the learning curve, I still encounter some difficulties. For instance, when I run my code to insert a figure:
\begin{figure}
\caption{Unemployment by Race}
\centering
\includegraphics[width=0.5\textwidth]
{C:/Users/ageis/Documents/Unemployment by Race.png}
\end{figure}
The figure is too small and LaTex puts the last half of my image's name into the pdf output beneath the figure.
I want the image to be at least 550 by 600 in pixels and the "by Race.png" bit in the space beneath the figure to be gone. What can I do?

Unemployment by Raceis responsible for the appearance ofby Race.pngbelow the image. The image is set to half of the\textwidth, if that is too small, you should use another width or thescaleoption – Sep 28 '17 at 04:47\usepackage{grffile}– Henri Menke Sep 28 '17 at 05:33
