两个图像一个在另一个上

I have two picture, one (Image 1) is the big one while the other (Image 2) is the small one that is a detail of the big one. I would like to do something like the zoom option (with tikzpicture) but instead to have the zoomed image image I just want to see the other image. Everything inside a figure with its caption.

我有两张照片，一张（图片1）是大图片，而另一张图片（图片2）是小图片，是大图片的细节。我想做像缩放选项（使用tikzpicture）之类的东西，而是拥有缩放的图像图像我只想看到另一个图像。图中的所有内容及其标题。

I made an example in case is difficult to understand what I want to do. Image 1 is my main image, the cross represents the schematised detail that is explained with Image 2. The two images are two .png.

我做了一个例子，以防很难理解我想做什么。图1是我的主图像，十字表示用图2解释的示意细节。两个图像是两个.png。

Is it possible?

可能吗？

Starting point. Now, you only need to connect the other anchors and decide the right position for the squares.

初始点。现在，您只需要连接其他锚点并确定正方形的正确位置。

\documentclass{report}
\usepackage{tikz}
\usepackage{graphicx}
\usepackage{lipsum}
\begin{document}
\lipsum[1]
\begin{figure}[h]\centering
\begin{tikzpicture}
\node[draw] (one) at (0,0){\includegraphics[width=6cm]{example-image-a}};
\node[anchor=north,draw,inner sep=0pt] (two) at ([xshift=-1cm]one.north west){\includegraphics[width=1cm]{example-image-b}};
\node[draw] (rect) at (-1,0){};
\draw (two.south east) -- (rect.south west);
\end{tikzpicture}
\caption{text}
\end{figure}

\lipsum[2]
\end{document}

#2

A solution using path picture to clip the zoom.

使用路径图片剪辑缩放的解决方案。

And as @Sigur said 'Starting point. Now, you only need to connect the other anchors and decide the right position for the' circles.

正如@Sigur所说'出发点。现在，您只需要连接其他锚点并确定'圈子的正确位置。

\documentclass[a4paper, 12pt]{article}
\usepackage{mwe}
\usepackage{tikz}

\begin{document}

    \begin{figure}[h!]
        \centering
        \includegraphics[width=.7\linewidth]{example-image}
        \caption[Text for the list of figures]{Text under the figure}
        \label{fig:theReference0}
    \end{figure}

    \begin{figure}[h!]
        \centering
        \begin{tikzpicture}
            [path image/.style={path picture={\node at (path picture bounding box.center) {\includegraphics[height=3cm]{#1}};}}]

            \node (img) {\includegraphics[width=.7\linewidth]{example-image}};
            \node (c1) [draw, circle, red, text width=.7cm] at (img.center) {};
            \draw [red] (c1.east) -- (img.east);
            \draw [path image=example-image-a,draw=red,thick] (img.east) circle (2cm);
        \end{tikzpicture}
        \caption[Text for the list of figures]{Text under the figure}
        \label{fig:theReference}
    \end{figure}
\end{document}

With picture environment:

有图片环境：

\documentclass{article}

\usepackage{graphicx}

\begin{document}

\noindent%
\setlength{\unitlength}{\textwidth}%
\begin{picture}(1,0.5)%
    \put(0.3,0){\includegraphics[width=.7\textwidth]{example-image}}%
    \put(0,0.33){\includegraphics[width=.2\textwidth]{example-grid-100x100bp}}%
    \put(0.0,0.33){\line(4,-1){.4}}
    \put(0.0,0.53){\line(4,-1){.4}}
    \put(0.2,0.33){\line(4,-1){.4}}
    \put(0.2,0.53){\line(4,-1){.4}}
    \put(0.4,0.23){\line(1,0){.2}}
    \put(0.4,0.43){\line(1,0){.2}}
    \put(0.4,0.23){\line(0,1){.2}}
    \put(0.6,0.23){\line(0,1){.2}}
\end{picture}%
