Using the same figure twice with no new number

Question

I have a figure that relates to two different issues discussed at very different point in a long document. Rather then send the reader back 50 pages to look up a figure, I would like to include the figure again at the later point.

However, I don't want it to appear twice in the list of figures or receive a new label number.

In this example, I would like it to appear in chapter 2 as figure 2.5 and again in chapter 4 as figure 2.5.

Is there a simple way to accomplish this? I am using Xelatex Version 3.1415926-2.5-0.9999.3 from the Texlive 2013 Arch Linux package.

With caption it's easy to avoid a caption going in the list of figures.
documentclass{book}
usepackage{caption}

newcommand{repeatcaption}[2]{%
  renewcommand{thefigure}{ref{#1}}%
  captionsetup{list=no}%
  caption{#2 (repeated from page pageref{#1})}%
  addtocounter{figure}{-1}% So that next figure after the repeat gets the right number.
}

newcommand{fakeimage}{fbox{Fake image}} % just for the example

begin{document}

frontmatter
listoffigures

mainmatter

chapter{A chapter title}

text

begin{figure}[htp]
centering
fakeimage
caption{A caption}label{figure:nice}
end{figure}

chapter{Another title}

text

begin{figure}[htp]
centering
fakeimage
caption{This is for the new figure}label{figure:dull}
end{figure}

begin{figure}[htp]
centering
fakeimage
repeatcaption{figure:nice}{A caption}
end{figure}

end{document}

It's up to you whether defining a macro holding the figure to be repeated or one for the caption text.

Here's one way, by stuffing the repeated figure content in a savedvbox.  However, in this case, the repeated figure will not be a float.  EDITED to resolve List of Figures issue.

documentclass{article}
newsaveboxsavefigure
begin{document}
listoffigures

begin{figure}[ht]
centering
framebox{first figure}
caption{First caption}
end{figure}

saveboxsavefigure{vbox{%
centering
framebox{second figure}
}}
begin{figure}[ht]
noindentusebox{savefigure}
caption{Second caption}
end{figure}

begin{figure}[ht]
centering
framebox{third figure}
caption{Third caption}
end{figure}

{centering

Figure 2: Second captionpar}
end{document}
