Preventing images from floating out of position

Question

I am using includegraphics to place images. These are basically answers to questions, therefore I would like to images to appear immediately below the question label. However, I the images just keep floating out of position and appear on top of the question label. How can I prevent this?

Sample code below:

\documentclass[12pt]{article}

\usepackage{graphicx}
\usepackage{epstopdf}

\DeclareMathSizes{11}{11}{11}{11}

\begin{document}

\setlength\parindent{0pt}

\textbf{1.} [Nothing to submit]

\textbf{2. (a)}
\includegraphics[scale=0.25]{graphs/fig_2a.eps}

\textbf{2. (b)}
\includegraphics[scale=0.25]{graphs/fig_2b.eps}

\end{document}

Answer 1

\includegraphics never floats, it is positioned in the same way as a letter such as X.

\textbf{2. (a)}
\includegraphics[scale=0.25]{graphs/fig_2a.eps}

Is the same as

\textbf{2. (a)} \includegraphics[scale=0.25]{graphs/fig_2a.eps}

so if the image fits, it puts a word space after the number then the image with its base on the baseline of the text.

As for text, if you want it to come underneath, put it in a new paragraph

\textbf{2. (a)}

\includegraphics[scale=0.25]{graphs/fig_2a.eps}

Although as noted in comments it is better to number automatically and just have

\item \includegraphics[scale=0.25]{graphs/fig_2a}

together with a suitable list definition.

[demo] just for the example, remove from real code.

\documentclass{article}

\usepackage[demo]{graphics}


\renewcommand\labelenumii{\theenumi. (\theenumii)}
\begin{document}

\begin{enumerate}

\item the first lot
\begin{enumerate}

\item \mbox{}\\\includegraphics{1.a}
\item \mbox{}\\\includegraphics{1.b}

\end{enumerate}

\item the second lot

\begin{enumerate}

\item \mbox{}\\\includegraphics{2.a}
\item \mbox{}\\\includegraphics{2.b}

\end{enumerate}
\end{enumerate}


\end{document}
