\subsection{Prvi zagon}
Pred prvim zagonom moramo na Raspberry Pi B+ priklopiti monitor ali televizijski sprejemnik preko HDMI kabla,
tipkovnico preko USB vrat ter kabel za internet preko ethernet vrat. Ko to storimo, pri\v{z}gemo Raspberry Pi B+
z vklopom napajalnika preko micro USB kabla v micro USB re\v{z}o in Rasbperry Pi B+ se pri\v{z}ge, aktivnost
nalaganja linux operacijskega sistema vidimo na ekranu/televizorju. Najprej se prika\v{z}e predstavitveno okno:
\begin{figure}
\centering
\includegraphics[scale=1.0]{slike/image_rPiBPlusSplashScreen.png}
\caption{Rasperry Pi B+ predstavitveno okno}
\end{figure}
\pagebreak
\end{document}
which produces result, described in 
. Obvisously, the inserted image is in wrong position, it should be placed in the centre (which is), but UNDER the text, not ABOVE It. What am I missing?
figureis a floating environment, that can move to avoid bad page breaks. See Keeping tables/figures close to where they are mentioned and How to influence the position of float environments like figure and table in LaTeX?. – Torbjørn T.

Read the second post I linked to above to fully learn what that means. – Torbjørn T. Mar 11 '15 at 16:45
