Thanks, all!  Probably I'm still missing something or not understanding how
this should work.  I tried to place two images on a page, so that both are
bottom aligned on a line halfway up the page (396bp).  I got LaTeX errors:

! LaTeX Error: Cannot determine size of graphic in egg.png (no BoundingBox).
...
! LaTeX Error: Cannot determine size of graphic in sheep.png (no
BoundingBox).

and the images both appear at the bottom of the page, not aligned. Here's
the doc I used:

\documentclass[11pt]{article}
\usepackage{graphicx}
\usepackage{textpos}
\usepackage{settobox}

\setlength{\TPHorizModule}{1bp}
\setlength{\TPVertModule}{\TPHorizModule}

\title{Image Placement Text}

\newlength{\imgheight}

\begin{document}

\newsavebox{\egg}
\sbox{\egg}{\includegraphics[scale=2.0]{egg.png}}

\newsavebox{\sheep}
\sbox{\sheep}{\includegraphics[scale=3.0]{sheep.png}}

\begin{textblock}{144}(72,396)
\settoboxtotalheight{\imgheight}{\egg}
\raisebox{\imgheight}{\usebox{\egg}}
\end{textblock}

\begin{textblock}{144}(288,396)
\settoboxtotalheight{\imgheight}{\sheep}
\raisebox{\imgheight}{\usebox{\sheep}}
\end{textblock}

\end{document}
