Group content side by side possibly spanning more than a single page

Question

I have data consisting of groups of key-value pairs and associated images. I'd like the key-value pairs to show in a table to the right of the images. Like this:

The above screenshot is produced by the following code:

\begin{minipage}[t]{.4\textwidth}
  \vspace{0pt}
  \includegraphics[width=\textwidth]{image}
  \includegraphics[width=\textwidth]{image}
\end{minipage}
\begin{minipage}[t]{.55\textwidth}
  \vspace{0pt}
  \begin{tabular}{ >{\bfseries \raggedleft}p{0.4\textwidth}<{:}  p{.6\textwidth}  }
    Key & Value \\
    Another key & 56.1481049 \\
    Ipsum bla & Lorem tutasee \\
    Kvalatit & Tip top \\
    Fordus tius & Lorem ipsum bla supresium vitales ektum eksaput doktinus mit dei fyrte granikus.\\
    Estimat is & 1337 \\
    Lokale & Viktualierum \\
  \end{tabular}
\end{minipage}

The code works as I want and several groups of tables and images can be placed after each other.

However unfortunately it seems that a minipage is restricted to a single page. Thus, if the images or the table takes more space than a single page, they will simply overflow the page and continue on into non-existence.

Is there any way that I can achieve what I want in a way so that if possible the tables aren't broken across several pages but in the cases where the minipages simply can't fit in a page they behave decently?

The above is a rough illustration of what I'd like to end op with. That is: the tabels/images only breaks on pages when they have to, otherwise they act like normal LaTeX floats.

You could take advantage of the new scrlayer packages in the new KOMA-script version (3.12). The column in the margin will continue, if necessary, on the next page. To me, this seems something rather new. However, you'd need longtable and I did not really test that. Just as an example I add some code, but you'll have to play with the width and the margins...

\documentclass[pagesize]{scrartcl}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{scrlayer-notecolumn, scrlayer-scrpage, graphicx, calc, longtable}


 \DeclareNewNoteColumn[font=\sffamily\footnotesize, width=3cm, 
 position=\oddsidemargin+1in+\textwidth-3cm+\marginparsep]{randnot}




\begin{document}
\begin{addmargin}[0cm]{3cm}
  \makenote[randnot]{%
    \protect\begin{longtable}{p{1.5cm}p{2cm} }
      Key & Value \\
      Another key & 56.1481049 \\
      Ipsum bla & Lorem tutasee \\
      Kvalatit & Tip top \\
      Fordus tius & Lorem ipsum bla supresium vitales ektum eksaput doktinus mit dei fyrte granikus.\\
      Estimat is & 1337 \\
      Lokale & Viktualierum \\
      \protect\end{longtable} }
  \includegraphics[width=\textwidth]{image}%
\end{addmargin}
\end{document} 

Answer 2

Here's a fairly simplistic solution using longtable, together with adjustbox to help with vertical alignment of the figures.

I have used a simple itemize list for your 'key-value' list, and used the enumitem to help with the formatting of it.

Note that the longtable environment will never break cells across pages, but will happily put page breaks between rows, which sounded like it was your main goal- the output should be almost exactly as it is in your mock-up, although you may get some bad pagination depending on the dimensions of your images.

% !arara: indent: {overwrite: yes, trace: yes, localSettings: yes}
\documentclass{article}
\usepackage[margin=1in]{geometry}
\usepackage{longtable}
\usepackage{graphicx}
\usepackage{enumitem}
\usepackage[export]{adjustbox}

\begin{document}

\begin{longtable}{p{.4\textwidth}p{.6\textwidth}}
    \includegraphics[width=\linewidth,valign=t]{example-image-a}
    \includegraphics[width=\linewidth,valign=t]{example-image-b}
    &
    \begin{itemize}[font=\bfseries,leftmargin=2.5cm]
        \item[Key] Value
        \item[Another key] 56.1481049
        \item[Ipsum bla] Lorem tutasee
        \item[Kvalatit] Tip top
        \item[Fordus tius] Lorem ipsum bla supresium vitales
              ektum eksaput doktinus mit dei fyrte granikus.
        \item[Estimat is] 1337
        \item[Lokale] Viktualierum
    \end{itemize}
\end{longtable}
\end{document}
