I would like to put a source under the caption of my figure. The only thing that is not working is when I put the URL, the caption and the URL don't stay in the middle.
Also \url{...}
didn't work by itself:
\begin{figure}[!h]
\centering
\includegraphics[width=70mm]{figure3}
\linespread{1}\caption{TITLE OF IMAGE
\\ \small{source by:\protect\url{www.aly-abbara.com/livre_gyn_obs/images/testosterone_DHT.html}}}
\label{figure3}
\end{figure}
{}
). I took the liberty to format you post a little. See this link for more details on available formatting.\documentclass
and the appropriate packages so that those trying to help don't have to recreate it.
