I know how to use a watermark on a full page in LaTeX reports, using for instance this code:

\usepackage{draftwatermark}
\SetWatermarkText{Confidential}
\SetWatermarkScale{5}

However, on my report, I would like to use watermark only on the pictures/graphics I included, so that the text is not hidden by anything. Only the pictures shall be marked with e.g. "Confidential".

Try xwatermark package. It allows you to specify the positions (on the page) of the watermarks - for graphics and text.

\documentclass{article}
\makeatletter
\usepackage[dvipsnames]{xcolor}
\usepackage[colorlinks,pdfview=FitB]{hyperref}
\usepackage[printwatermark]{xwatermark}
\thispagestyle{empty}

% Local watermark locations:
\watermarkpaths{{./}{./Graphics/}}

% One combined watermark (graphics + text). This is what you need. The key
% to note here is 'textontoppic':
\newwatermark[
  oddpages,coordunit=pc,fontfamily=put,textcolor=red,
  fontsize=2cm,textalign=center,textangle=29,picangle=0,
  textxpos=-1,textypos=1,picxpos=0,picypos=0,
  textontoppic,picbb=20 21 590 400,
  picscale=.6,picfile=comet1,picfileext=pdf
]{Confidential}

% Repeated combined watermark (graphics + text):
\xwmgetpicturesize[scale=.5,viewport=20 21 590 400]{comet1}
\def\twidth#1{.5\paperwidth#1\widthofpic}
\def\theight#1{.5\paperheight#1\heightofpic}
\repeatwatermarks[Page=\thepage]{%
  oddpages,coordunit=pc,picbb=20 21 590 400,picscale=.5,picfile=comet1,
  textontoppic,fontsize=2.5cm,textcolor=white
}{%
  picxpos=-\twidth{+}/2,picypos=-\theight{+}/2,
  textxpos=-\twidth{+}/2,textypos=-\theight{+}/2;
  picxpos=-\twidth{+}/2,picypos=\theight{-}/2,
  textxpos=-\twidth{+}/2,textypos=\theight{-}/4;
  picxpos=\twidth{-}/2,picypos=-\theight{+}/2,
  textxpos=\twidth{-}/2,textypos=-\theight{+}/2;
  picxpos=\twidth{-}/2,picypos=\theight{-}/2,
  textxpos=\twidth{-}/2,textypos=\theight{-}/4
}
\makeatother

Grabbing some code from Resize large images that exceed page margin whilst respecting existing scale, a redefinition of \includegraphics can place a "confidentiality notice" over all images, or selectively exclude the notice:

enter image description here

\documentclass{article}
\usepackage{xparse,graphicx,xcolor}% http://ctan.org/pkg/{graphicx,xcolor}
\newcommand{\confidential}{\color{red!80}\LARGE\bfseries CONFIDENTIAL}% Confidentiality notice
\newsavebox\IBox
\let\IncludeGraphics\includegraphics
\RenewDocumentCommand{\includegraphics}{s O{} m}{%
  \sbox\IBox{\IncludeGraphics[#2]{#3}}%
  \ooalign{\usebox\IBox% Print graphic
    \IfBooleanTF{#1}{}{% Confidential or not
      \cr\hss%
      \raisebox{.1\ht\IBox}{\resizebox{.8\wd\IBox}{.8\ht\IBox}{\confidential}}% Print confidentiality notice
      \hss}}}%
\begin{document}
\includegraphics[width=20pt]{example-image-a}
\includegraphics[height=30pt]{example-image-b}
\includegraphics[width=10em,height=10em]{example-image-c}
\includegraphics*[scale=.2]{example-image-a}
\renewcommand{\confidential}{\color{green!70}\rule{10pt}{10pt}}% Change confidentiality notice
\includegraphics[width=15ex]{example-image-b}
\end{document}

xparse provides the interface for the modified version of \includegraphics. It now provides a starred variant \includegraphics* that prints an image without a "confidentiality notice".

The "confidentiality notice" is centred and stretched to fit over 80% of the image height/width.
