Graphics, Figures & Tables ⇒ Resolving caption outside float error message

[bgreen]

I’m very new to LaTeX .

I want to format a series of social history interviews, which can include 15 to 20 photos, sometimes , two or 3 beside each other. I also want to keep image resolution as high as possible.
Here is my coding effort to date, with a single 300 x 400 image, which produced this error: “! LaTeX Error: \caption outside float.”

Code: Select all

\documentclass{article}

\usepackage{titlesec}
\usepackage[a4paper, total={6in, 8in}]{geometry}
\usepackage{graphicx} 
\usepackage[english] {babel}
\usepackage {blindtext}
\pagestyle {empty}
\titleformat*{\section}{\fontsize{12}{14}\selectfont}
\graphicspath{ {D:/A/BB/DD/} }
\begin{document}

I am seeking advice regarding packages and code to (1) resolve the specific error. In an ideal world I’d like the photo topic above the image and the photo source below, but suspect this is more complicated in LaTeX , so would be happy with captions below the photo; (2) advice about code for two images side by side, with captions below each image and (3) is it possible to hyperlink photos, so higher resolution images can be viewed elsewhere on a webpage.
Any advice is appreciated.

Hello bgreen,

Welcome to the world of LaTeX! Let's address the specific error you're encountering and then move on to your other questions.

The error "! LaTeX Error: \caption outside float" typically occurs when you use the \caption command outside a floating environment like figure. To resolve this, ensure that your \caption command is placed inside the figure environment. Here's a modified example for a single image:

Code: Select all

\documentclass{article}
\usepackage{graphicx}

\begin{document}

\begin{figure}
  \centering
  \includegraphics[width=0.5\textwidth]{your_image.jpg}
  \caption{Your caption here.}
  \label{fig:single_image}
\end{figure}

\end{document}

This code creates a floating figure with a centered image and a caption below it.

Now, for your other questions:

For two images side by side, you can use the subfigure or subcaption package. Here's an example:

Code: Select all

\documentclass{article}
\usepackage{graphicx}
\usepackage{subcaption}

\begin{document}

\begin{figure}
  \centering
  \begin{subfigure}{0.45\textwidth}
    \includegraphics[width=\linewidth]{image1.jpg}
    \caption{Caption for image 1.}
    \label{fig:subfig1}
  \end{subfigure}
  \hfill
  \begin{subfigure}{0.45\textwidth}
    \includegraphics[width=\linewidth]{image2.jpg}
    \caption{Caption for image 2.}
    \label{fig:subfig2}
  \end{subfigure}
  \caption{Overall caption for the two images.}
  \label{fig:two_images}
\end{figure}
\end{document}

To hyperlink images, you can use the \href command from the hyperref package:

Code: Select all

\documentclass{article}
\usepackage{graphicx}
\usepackage{hyperref}

\begin{document}

\begin{figure}
  \centering
  \href{https://example.com/high_res_image.jpg}{\includegraphics[width=0.5\textwidth]{your_image.jpg}}
  \caption{Caption with a hyperlink to a high-resolution version.}
  \label{fig:hyperlink_image}
\end{figure}

\end{document}

Make sure to replace the placeholder URLs and image filenames with your actual information. I hope this helps! Let me know if you have further questions.

Rene,

Firstly, many thanks for a comprehensive and helpful reply. I'll try the second and third code suggestions as I get to examples in the document. I do have two additional questions at the moment, which can be separate topics if preferred:

Thanks again.
