This the first document I am making in LaTeX and I am having some problems with the images.
As you can see, I placed the figure in section "Metologia y Procedimiento" but it goes to the top of that page right after the first image in section "Marco Teorico". I saw some answers on other forums/pages but they required to get rid of the captions (as I understood it) but the captions are required by my professor.
\documentclass[12pt,letterpaper]{report}
% % %Package loading
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[spanish]{babel}
\usepackage{lmodern}
\usepackage{graphicx}
\usepackage{fullpage}
\usepackage{gensymb}
Here is the part that is giving me problems (i substituted the text for something random to avoid being lengthy):
\section{Marco Teórico}
Random Paragraph
\begin{figure}
\centering
\includegraphics[width=0.57\textwidth]{diferenciales}
\caption[Long caption]{Elemento de fuerza hidrostática sobre una placa plana}
\label{fig: diferenciales}
\end{figure}
\section{Objetivos}
\begin{itemize}
\item Item 1
\item Item 3
\item Item 3
\end{itemize}
\section{Metodología y Procedimiento}
Random paragraph
\begin{figure}
\centering
\includegraphics[width=0.4\textwidth]{Equipo}
\caption[Long caption]{Equipo utilizado para la medición de fuerzas hidroestáticas}
\label{fig: equipo}
\end{figure}
\chapter{Datos y Ejemplos del Laboratorio}
Thank you in advance.



figureenvironment is a "floating" environment, which means that LaTeX moves it around the document where it fits best. If you absolutely want it to be placed where you said, just use thecenterenvironment instead offigure. If you do that and still want captions, you can look into thecapt-ofpackage. – Paul Gessler Feb 16 '15 at 20:51\usepackage{flafter}– David Carlisle Feb 16 '15 at 20:56
