Make text next to picture vertically centered

Question

I wish to display a small image (included by includegraphicx) immediately followed by a short text. The problem I have is that the text is not vertically centered relatively to the image. I found a solution using TikZ but that's probably overkill. Besides my TikZ solution is not easily rescalable.

I found many tips for vertical centering on this forum but they were all dealing with rather different situations.

A PDF output summarizes it all :

Here is the source code : I have two files, main.tex and badge.tex.

Contents of main.tex :

\documentclass{article}
\usepackage{tikz}
\usepackage{calc}

\newcommand*{\badge}{%
  \includegraphics[height=\heightof{M}+\heightof{M}]{badge}%
}


\begin{document}

Here is the kind of output I don't want :

{\Huge \badge~Hello World}

\vspace*{1cm}
And here is the kind of output I want :

\begin{tikzpicture}
\node[inner sep=0pt] (badge) at (0,0)
    {\includegraphics[width=.14\textwidth]{badge.pdf}};
\node at (3.2,0) {\Huge Hello World};    
\end{tikzpicture}

\end{document}

Contents of badge.tex :

\documentclass{standalone}
%\documentclass{article}
\usepackage{xcolor}
\usepackage{tikz}
