Insert vertical spacing after all \includegraphics

Question

I'm using tcolorbox which recommends not using float environments like figure and table inside a box, and instead suggests directly using includegrapghics and tabular combined with \captionof.

I guess one of the things a figure environment does is adding vertical spacing at the end. How can I achieve a similar thing for all my includegraphics? I can of course add vspace but is there a property I can set globally?

Do you want to add the space inside of the tcolorbox? If so, you can use the trim option for the \includegraphics command and set it globally via \setkeys{Gin}{trim=}.

\documentclass[12pt, a4paper]{scrartcl}
\usepackage{graphicx, tcolorbox}

\begin{document}

Here is a figure 
\begin{tcolorbox}[width=8cm]
    \centering
    \includegraphics[scale=0.5]{example-image-a}
\end{tcolorbox}
without vertical spacing of 2cm \\ 

\setkeys{Gin}{trim=0pt -2cm 0pt -0cm}

And a figure 
\begin{tcolorbox}[width=8cm]
    \centering
    \includegraphics[scale=0.5]{example-image-b}
\end{tcolorbox}
with vertical spacing of 2cm below \\

\end{document}

This can add (or subtract, depending on the sign) a vertical space (here 2cm) above or below the image. However this only adds space inside of the tcolorbox:
