Latex - Inserting a reference in a figure's caption

Question

In Latex, I want to add a reference in the legend of a figure, like:

\\begin{figure}
   ...
   \\caption{This is the legend of this figure (reprinted from \\cite         


        

Answer 1

As the accepted answer seems rather hacky (and also didn't work for me) I will post my solution for the problem:

\begin{figure}
  ...
  \caption[Cap for listoffigures]{Cap below figure with cite \cite{source}}
  ...
\end{figure}

This compiles without errors and warnings.
