# Unwanted bounding box around an image [duplicate]

I use TeXmaker and I try to insert an image with the command \includegraphics. The problem is that when I compile it, i have a border around my image and I don't want that. I tried everything that I looked up on Google, but still nothing works for me. Can anyone here help me? The problem occurs with .png screenshots and .eps files that I use. Below you can see what I mean.

# EDIT:

I compile my text with LuaLaTeX, if that matters.

\begin{figure}
\centering
\includegraphics[scale=0.5]{example-image}
\caption{Μετατροπή από την κλίμακα mel στη συχνότητα}
\label{fig:mel2freq}
\end{figure}

• \includegraphics doesn't add a box, so either it is in the image, or you have \fbox or framed or similar around the image inclusion, but if you do not show any code it is hard to guess. – David Carlisle Nov 2 '17 at 17:32
• try with example-image (a test file in the tex distributions, do you still get a frame? if you do please post in your question (not n comments) a complete test document so people can debug – David Carlisle Nov 2 '17 at 19:26
