Embed small image within a line of text

Question

I am having trouble perfectly getting an image to embed within a line of text. Ideally, the image is to be scaled to the correct size so that it fits within the line of text. This is as far as I've gotten. While it is close, the image is too tall. Any ideas? Thanks!

\documentclass[preprint2]{aastex}

\usepackage{graphicx}

\newcommand*{\img}[1]{%
    \raisebox{-.02\baselineskip}{%
        \includegraphics[
        height=\baselineskip,
        width=\baselineskip,
        keepaspectratio,
        ]{#1}%
    }%
}

\begin{document}

\begin{enumerate}
\item When ready, click `record \img{Record.png}'.  There will be a three second period before the actual data collection begins.
\end{enumerate}

\end{document}

Here's an image if what I get with this:

Like this?

\documentclass{article}
\usepackage{graphicx,calc}
\newlength\myheight
\newlength\mydepth
\settototalheight\myheight{Xygp}
\settodepth\mydepth{Xygp}
\setlength\fboxsep{0pt}
\begin{document}
  This is some arbitrary \raisebox{-\mydepth}{\fbox{\includegraphics[height=\myheight]{tiger}}} line of uninteresting text.
\end{document}

As written, this will not adapt to font size changes within the document. You can, however, define a new \inlinegraphics{} command which does so:

\documentclass{article}
\usepackage{graphicx,calc}
\newlength\myheight
\newlength\mydepth
\settototalheight\myheight{Xygp}
\settodepth\mydepth{Xygp}
\setlength\fboxsep{0pt}
\newcommand*\inlinegraphics[1]{%
  \settototalheight\myheight{Xygp}%
  \settodepth\mydepth{Xygp}%
  \raisebox{-\mydepth}{\includegraphics[height=\myheight]{#1}}%
}
\begin{document}
  This is some arbitrary \raisebox{-\mydepth}{\fbox{\includegraphics[height=\myheight]{tiger}}} line of uninteresting text.

  This should adapt \inlinegraphics{example-image-a}.

  \Huge Will this adapt \inlinegraphics{example-image-b} nicely?

  \tiny That is yet to be \inlinegraphics{example-image-a} seen.
\end{document}

Answer 2

Simply lower from 0.3\baselineskip:

\documentclass{article}%[preprint2]{aastex}

\usepackage{graphicx}

\newcommand*{\img}[1]{%
    \raisebox{-.3\baselineskip}{%
        \includegraphics[
        height=\baselineskip,
        width=\baselineskip,
        keepaspectratio,
        ]{#1}%
    }%
}

\begin{document}

\begin{enumerate}
\item When ready, click `record \img{Vinyl.png}'. There will be a three second period before the actual data collection begins.
\end{enumerate}

\end{document}
