How to insert "source" below image

I have to mention the source of the image that I am using in my text.

How can I write the source below any image just like its shown in the above figure? I don't want to mention the source alongside caption. I am using following code for inserting images and it would be helpful if anyone can tell the codes for writing source which is compatible with this one:

\begin{figure}[ht]
\includegraphics[width=\linewidth]{image}
\caption{Letter e}
\end{figure}


I have seen Add source to figure caption but it doesn't help much.

\documentclass{article}
\usepackage{graphicx}
\usepackage[x11names]{xcolor}

\usepackage{url}

\begin{document}
\begin{figure}[!h]
{Source: \url{http://tex.stackexchange.com/}}

\end{figure}
\end{document}


edit: or with stackengine

\documentclass{article}
\usepackage{graphicx}

\usepackage{stackengine}
\usepackage{url}

\begin{document}
\begin{figure}[hb]
\centering
\def\stackalignment{r}
\stackunder{\includegraphics[width=\linewidth]{example-image-b}}%
{\scriptsize%
Source: \url{http://tex.stackexchange.com/}}
\end{figure}
\end{document}


Set your image in a tabular that has a single right-aligned column:

\documentclass{article}

\usepackage{graphicx}

\newcommand{\imagesource}[1]{{\footnotesize Source: #1}}

\begin{document}

\begin{figure}
\centering
\begin{tabular}{ @{} r @{} }
\includegraphics[width = .5\linewidth]{example-image} \\
\imagesource{Image A}
\end{tabular}
\end{figure}

\end{document}
