How to add captions and a label to an image

How to add a caption

It's really easy, just add the \caption{a caption} and inside the braces write the text to be shown. The placement of the caption depends on where you place the command; if it'a above the includegraphics then the caption will be on top of it, if it's below then the caption will also be set below the figure.

CODE

\begin{figure}[t]

                            \caption{this is a logo}

                           \includegraphics[width=0.6\textwidth]{USI-LOGO.png}

                            \end{figure}

How to add a label

Figures, just as many other elements in a LATEX document (equations, tables, plots, etc) can be referenced within the text. This is very easy, just add a label to the figure environment, then later use that label to refer the picture.

CODE

\begin{figure}[h]

                              \includegraphics[width=0.25\textwidth]{USI-LOGO.png}

                              \caption{the main building}

                              \label{fig1}

                              \end{figure}
