numbered ornament as section title

Question

I am trying to recreate a kind of numbered ornament in my section labels. The section number comes from a specific font, then is transformed (rotated) and then placed within an image.

For example, section number 23 would have this image of a tag and string with the number 23 inside it. And then on the line beneath, the section title.

My MWE is completely lame since I don't know where to begin on this question, but some kind of MWE is required, so:

\documentclass[11pt,oneside]{article}
\begin{document}
\section{Title of First Section}%this would have a tag with number 1 inside.
\section{Title of Second Section}%this would have a tag with number 2 inside inside.
\end{document}

Update — using a .png

As requested, this is an update using an image, here a .png because it supports the alpha channel and helps make the image smaller. I have cropped the image you supplied, and then made the remaining background transparent.

The image is then imported and scaled down. Scaling it is preferable because scaling a bigger image holds greater quality than using an image with already the desired dimensions.

I have added an extra node, besides the one holding the image, to place the actual number. In order to see the new result, replace the \fancynumber command with the following code:

\newcommand\fancynumber{%
\tikz[baseline=(a)] {
    \node (a) at (0,0) {\includegraphics[scale=.35]{card}};
    \node[%
        rotate=-32,
        font=\bfseries\sffamily\Large,
        ] at ($(a.center)!.3!(a.east)$) {\thesection};
}%
}

Remember that if you place the png in the same folder as your .tex file, you don't need to specify the path or the extensions, therefore \includegraphics[scale=.35]{card}. And here's the result:

Original answer

Here's a solution that uses TikZ, heavily adapted from Jake's answer.

Output

Code

\documentclass[11pt,oneside]{article}
\usepackage{titlesec}
\usepackage{tikz}

\usetikzlibrary{calc,shapes.symbols, backgrounds, shadows}

\tikzset{
  myshadow/.style={opacity=.25,shadow xshift=-0.005, shadow yshift=-0.07},
}

\newcommand\fancynumber{%
\tikz[baseline=(a.north east)] {
    \node [draw,
        minimum width=1cm,
        minimum height=6mm,
        shape=signal,
        fill=white,
        rotate=-30,
        drop shadow={myshadow},
        signal to=west,
        font=\bfseries\sffamily\large,
        rounded corners=.5mm] (a) at (0,0) {\thesection};
    \draw[fill=gray!25] ($(a.west)!.2!(a.east)+(0,-.5pt)$) circle (2pt);
    \path ($(a.west)!.2!(a.east)$) edge[line cap=round,line width=1mm, out=200,in=-15, looseness=1.5] ++(-.5,.5) coordinate (b);
    \begin{scope}[on background layer] 
    \path ($(a.west)!.2!(a.east)$) edge[line cap=round,line width=1mm, out=100,in=5, looseness=1.5] ++(-.5,.5);
    \end{scope}
}%
}

\renewcommand*{\thesection}{\arabic{section}}
\titleformat{\section}{\large}{\fancynumber}{.2cm}{}

\begin{document}
%\chapter{My first chapter}
\section{First section}
\section{Second section}
\setcounter{section}{24}
\section{25th section}
\end{document}
