Vertical alignment of arrow between images

Question

I'm struggling with template given for my article. I've got four images and I'd like to place right arrow between them.

Problem is that arrows should be in the middle instead of at the bottom.

\Teaser{
    \TeaserImage{orig.png}
    \Rightarrow
    \TeaserImage{grid.png}
    \Rightarrow
    \TeaserImage{map.png}
    \Rightarrow
    \TeaserImage{predictions.png}
}

Commands Teaser and TeaserImage are defined in template like so

\newcommand{\Teaser}[1]{\global\HaveTeasertrue\def\@Teaser{#1}}
\newcommand{\TeaserImage}[1]{\includegraphics[height=1in]{#1}}

I've tried to use vspace, but without any luck.

Answer 1

\documentclass{article}
\usepackage[margin=50pt]{geometry}
\usepackage{graphicx,amssymb}
%\newcommand{\Teaser}[1]{\global\HaveTeasertrue\def\@Teaser{#1}}
\newcommand{\TeaserImage}[1]{\raisebox{%
  .5\dimexpr-\height+\ht\strutbox-\dp\strutbox}{%
  \includegraphics[height=1in]{#1}}}
\begin{document}
$%\Teaser{
    \TeaserImage{example-image}
    \Rightarrow
    \TeaserImage{example-image-a}
    \Rightarrow
    \TeaserImage{example-image-b}
    \Rightarrow
    \TeaserImage{example-image-c}
$%}
\end{document}

Answer 2

Just spelling out my comment.

\documentclass{article}
\usepackage{graphicx}
\usepackage[margin=1in]{geometry}
\newcommand{\TeaserImage}[1]{\vcenter{\hbox{\includegraphics[height=1in]{#1}}}}
\begin{document}
$\TeaserImage{example-image-duck}
    \Rightarrow
    \TeaserImage{example-image-duck}
    \Rightarrow
    \TeaserImage{example-image-duck}
    \Rightarrow
    \TeaserImage{example-image-duck}$
\end{document}
