Picture and animateinline

Question

I would like to have an animation (consisting of three pictures pic-0.jpg, pic-1.jpg, pic-2.jpg) with additional elements added on the top of the animation. What am I doing wrong? And how can I do it right?

\documentclass[xcolor={dvipsnames,svgnames,table},11pt]{beamer}
\usepackage{animate}
\begin{document}
\begin{frame}

\only<1>{Text}
\only<2> 
{\begin{animateinline}[autoplay,loop]{6}
   \multiframe{3}{i=0+1}{ 
   \begin{figure}[h!]
   \centering
   \setlength{\unitlength}{0.1\textwidth}
   \begin{picture}(0,0)
   \put(-6,-3){\includegraphics[height=0.8\columnwidth]{pic-\i} }
   \put(4.5,-2){$x$}
   \end{picture}
   \end{figure} }
 \end{animateinline}      }  

\end{frame}
\end{document}

Several issues: (1) figure environment inside animateinline environment; (2) zero picture size — AlexG, Jan 31 '18 at 14:09
The error is: package animate error content of first frame must not have zero width — Markow, Jan 31 '18 at 23:06

\begin{picture}(0,0) ... \end{picture} produces a box with zero dimensions, but animate wants non-zero size boxes in order to produce animation frames.

TikZ is better suited for annotating external graphics files. Dedicated TikZ-based packages exist for image annotation, e. g. callouts on CTAN, and non-CTAN onimage, introduced ↗here. I prefer the latter. It can be downloaded as onimage.dtx↗here. Run pdflatex twice on it to get onimage.sty and the documentation onimage.pdf.

The figure environment should be moved out of the animateinline environment.

\documentclass{beamer}
\usepackage{animate}
\usepackage{onimage}
\begin{document}
\begin{frame}{Annotated animation}
  \only<1>{Text}
  \only<2>{% 
    \begin{figure}\centering
    \begin{animateinline}[autoplay,loop]{1}
      \begin{tikzonimage}[width=0.6\columnwidth]{example-image-a}[tsx/show help lines]
        \draw (0.5,0.5) [<-]-- (0.3,0.4) node [anchor=east] {centre};
      \end{tikzonimage}
    \newframe
      \begin{tikzonimage}[width=0.6\columnwidth]{example-image-b}[tsx/show help lines]
        \node [anchor=south west] at (0,0) {lower left};
      \end{tikzonimage}
    \newframe
      \begin{tikzonimage}[width=0.6\columnwidth]{example-image-c}[tsx/show help lines]
        \node [anchor=north east] at (1,1) {upper right};
      \end{tikzonimage}
    %\newframe

    %\multiframe{3}{i=0+1}{
    %  \begin{tikzonimage}[width=0.6\columnwidth]{pic-\i}[tsx/show help lines]
    %    ... 
    %  \end{tikzonimage}
    %}
    \end{animateinline}%
    \caption{annotated animation}
    \end{figure}
  }
\end{frame}
\end{document}
