Image source below image and longer than its width

Question

This is a follow-up to the answer from https://tex.stackexchange.com/a/412010/221716

As with the original question, I'd like to include the source text under the image. However, the URL is longer than the image's width, and the environment is a wrapfigure.

Latex source:

\documentclass{book}
\usepackage{graphicx}
\usepackage{wrapfig}
\usepackage{stackengine}
\usepackage{xurl}
\usepackage{lipsum}
\begin{document}
\begin{wrapfigure}
  {r}{.25\textwidth}
  \centering
  \def\stackalignment{r}\stackunder{ %
    \includegraphics[width=.25\textwidth]{example-image-b} %
  }{\tiny Source: \url{https://www.example.org/very/very/very/very/very/very/very/long/url}}
  \caption{My Caption}
\end{wrapfigure}
\lipsum
\end{document}

As a result, the URL does not take into account the width of the environment. As a result, the picture is misaligned, and the URL is not wrapped inside the appropriate width:

Surprisingly, removing \stackalignment{r} correctly wraps the URL but removes the picture:

Is it feasible to have the picture and the source aligned and wrapped correctly? Furthermore, because the text is so small, may the vertical space of the URL be reduced? Thanks

the answer you link to is so nice and shows a complete example and uses a graphic that is generally available. One can directly copy&paste and try. Why do you drop all this and make your code untestable? — Ulrike Fischer, Feb 01 '23 at 17:18

Like this?

\usepackage{graphicx}
\usepackage{wrapfig}
\usepackage{stackengine}
\usepackage{xurl}
\usepackage{etoolbox}
\BeforeBeginEnvironment{wrapfigure}{%
    \setlength{\intextsep}{0pt}} % remove superfluous vertical space above/below wrapfigure
\usepackage{lipsum}
\begin{document}
\begin{wrapfigure}{r}{.25\textwidth}
\def\stackalignment{r}\stackunder{%
\includegraphics[width=\linewidth]{example-image-duck}%{image.png} %
    }{\scriptsize 
    \parbox[t]{\linewidth}{% <... needed
    Source: \url{https://www.example.org/very/very/very/very/very/very/very/long/url}}
   }
  \caption{Caption of wrapfigure}
\end{wrapfigure}
\lipsum
\end{document}

Awesome! Thanks. – Carlo Corradini Feb 01 '23 at 17:46
Only one doubt: what is the purpose of etoolbox and BeforeBeginEnvironment? Thanks – Carlo Corradini Feb 01 '23 at 17:46

@CarloCorradini, they insert before each wrapfig command \setlength{\intextsep}{0pt}, whic remove vertical space above/below figure. For test delete this part of code and see difference. See edited answer. – Zarko Feb 01 '23 at 17:51
