How to change the name Figure to greek Εικόνα

Question

I would like to change the name "Σχήμα" to "Εικόνα" as you can see in the screenshot. Without babel it would be easy since I change the document element Figure to other word. How can I do it in babel. I tried \addto\captionsenglish{\renewcommand{\figurename}{Εικόνα.}. But it can not do it. My code is

\documentclass[12pt]{report}

\usepackage[english,greek]{babel}

\usepackage{graphicx}

\usepackage{tabularx}

\usepackage{multirow}


\begin{figure}[H]

\includegraphics[width=20cm]{PictureA.jpg}

\centering \selectlanguage{greek}

\caption{Αρχική κατάσταση. Μετωπιαία όψη.}

\end{figure}

\end{document}

Answer 1

Currently (≥ 3.51) the best option is \setlocalecaption, as shown:

\documentclass[12pt]{report}

\usepackage[english,greek]{babel}

\setlocalecaption{greek}{figure}{Εικόνα}

\usepackage{graphicx}

\begin{document}

\begin{figure}
\includegraphics[width=20cm]{PictureA.jpg}
\centering \selectlanguage{greek}
\caption{Αρχική κατάσταση. Μετωπιαία όψη.}
\end{figure}

\end{document}

This generates the following caption:
