Answer 1

I modified the headline template of the split theme. You can set your custom header image via

\newcommand\headerimage{<path to image>}

MWE:

\documentclass{beamer}
\usepackage{mwe}
\newcommand\headerimage{example-image-a}
\usetheme{Copenhagen}
\makeatletter
\setbeamertemplate{headline}
{%
  \leavevmode%
  \@tempdimb=2.4375ex%
  \ifnum\beamer@subsectionmax<\beamer@sectionmax%
    \multiply\@tempdimb by\beamer@sectionmax%
  \else%
    \multiply\@tempdimb by\beamer@subsectionmax%
  \fi%
  \ifdim\@tempdimb>0pt%
    \advance\@tempdimb by 1.825ex%
    \begin{beamercolorbox}[wd=.5\paperwidth,ht=\@tempdimb]{section in head/foot}%
      \vbox to\@tempdimb{\vfil\insertsectionnavigation{.5\paperwidth}\vfil}%
    \end{beamercolorbox}%
    \begin{beamercolorbox}[wd=.5\paperwidth,ht=\@tempdimb]{subsection in head/foot}%
      \includegraphics[width=.5\paperwidth,height=\@tempdimb]{\headerimage}
    \end{beamercolorbox}%
  \fi%
}
\makeatother
