Graphics Floating Around

I have wrote this piece of LaTeX code

\chapter{Datenmodellierung}
\paragraph{Fremdschlüssel}
\includegraphics[width=0.4\textwidth]{Resources/Included Graphics/foreign_keys_example.png}

\paragraph{Integritätsprüfung via Checks}
\includegraphics[width=0.4\textwidth]{Resources/Included Graphics/integrity_checking.png}


and expected it to look be a heading, then a picture in the next line, then a heading again (in a new line), and finally the second graphic in yet another line.

Unfortunately, it looks like this:

So maybe using figures hel ... no, it doesn't:

\chapter{Datenmodellierung}
\paragraph{Fremdschlüssel}
\begin{figure}
\includegraphics[width=0.4\textwidth]{Resources/Included Graphics/foreign_keys_example.png}
\end{figure}

\paragraph{Integritätsprüfung via Checks}
\begin{figure}
\includegraphics[width=0.4\textwidth]{Resources/Included Graphics/integrity_checking.png}
\end{figure}


I of course googled the problem and found a solution: Inserting float barriers and using the package placeins.

I inserted them like this

\chapter{Datenmodellierung}
\paragraph{Fremdschlüssel}
\FloatBarrier
\begin{figure}
\includegraphics[width=0.4\textwidth]{Resources/Included Graphics/foreign_keys_example.png}
\end{figure}

\FloatBarrier
\paragraph{Integritätsprüfung via Checks}
\FloatBarrier
\begin{figure}
\includegraphics[width=0.4\textwidth]{Resources/Included Graphics/integrity_checking.png}
\end{figure}


and somehow it got even worse:

I'd like to stop stuff from floating around altogether. Is this possible?

I already use the package float and Hs behind table declarations (\begin{table}[H]) to stop them from floating all over the place. However, that doesn't help with the graphics floating around.

The article type is report.

• Don't use the figure environment, if you want to place a graphic object just there with no caption. There's no rule that mandates \includegraphics to be in a figure environment. – egreg Jun 18 '16 at 22:36
• If I don't use figures, the float barriers don't have any effect at all. – UTF-8 Jun 18 '16 at 22:50
• And what would be the purpose of \FloatBarrier if there's nothing to float around? – egreg Jun 18 '16 at 23:00

The standard behavior of \paragraph is to print the heading in-line.
\paragraph{Fremdschlüssel}\mbox{}\\*

• @UTF-8 If you don't want them to float, just don't use the figure environment (and don't give them captions). – egreg Jun 19 '16 at 9:11
• Ah, when writing a report, I can center graphics without putting them into figures. I didn't know this is possible. It doesn't seem to be possible when using document type beamer, though. – UTF-8 Jun 19 '16 at 12:23
