Image inside another image

Question

I currently have some LaTeX code to have multiple images side by side:

begin{figure*}
begin{center}
includegraphics[height=2cm]{foo11.jpg}
includegraphics[height=2cm]{foo12.jpg}
includegraphics[height=2cm]{foo21.jpg}
includegraphics[height=2cm]{foo22.jpg}
end{center}
caption{my caption.}
end{figure*}

I would now like to add a small inset, inside for example foo12.jpg and foo22.jpg. For example, having the image bar12.jpg as a small thumbnail in the top-right corner of foo12.jpg and having the image bar22.jpg as a small thumbnail in the top-right corner of foo22.jpg.

Of course, my goal is not to do that using Photoshop (or any external tool/script) but to do it directly in LaTeX. I guess this should be doable (since with Acrobat we can place images wherever we want in a PDF, and since LaTeX figures are "floating"), but have no idea how and I can't find any resource to help.

If you know the dimensions of the images, then you can easily do this with a raised overlap.

documentclass{article}
usepackage{graphicx}% http://ctan.org/pkg/graphicx
begin{document}
begin{figure}
  centering
  setbox1=hbox{includegraphics[height=2cm]{example-image-b}}
  includegraphics[height=2cm]{example-image-a}llap{includegraphics[height=1cm]{example-image-c}}
  includegraphics[height=2cm]{example-image-a}llap{raisebox{1cm}{includegraphics[height=1cm]{example-image-c}}} 
  includegraphics[height=2cm]{example-image-b}llap{makebox[wd1][l]{includegraphics[height=1cm]{example-image-c}}}
  includegraphics[height=2cm]{example-image-b}llap{makebox[wd1][l]{raisebox{1cm}{includegraphics[height=1cm]{example-image-c}}}}
  caption{My caption.}
end{figure}
end{document}

I've used the example images from the mwe package, and knowing that the heights will be 1cm, raising by 1cm will fill the 2cm of the original image. However, if you don't know the heights, one can always box the contents and extract the height, as I did with setbox1=hbox{...} and using wd1 (width of box 1). There might be better ways of doing this.

Borrowing some of the excellent code from Drawing on an image with TikZ you can achieve this using tikz

Code

documentclass{article}
usepackage{tikz}
usepackage{graphicx}

begin{document}

begin{figure}[!htb]
    centering
    begin{tikzpicture}
        node[anchor=south west,inner sep=0] (image) at (0,0) {includegraphics[width=textwidth]{mushroom}};
        begin{scope}[x={(image.south east)},y={(image.north west)}]
            draw[help lines,xstep=.1,ystep=.1] (0,0) grid (1,1);
            foreach x in {0,1,...,9} { node [anchor=north] at (x/10,0) {0.x}; }
            foreach y in {0,1,...,9} { node [anchor=east] at (0,y/10) {0.y}; }
            node[anchor=south west,inner sep=0] (image) at (0.5,0.7) {includegraphics[width=0.1textwidth]{tux}};
        end{scope}
    end{tikzpicture}
    caption{Find that penguin!}
end{figure}
end{document}

The stackengine package has this feature. UPDATED for newer syntax. The command featured here is stackinset. The six arguments to inset content are stackinset{}{}{}{}{}{} The value of of l, c, or r determines whether the H-offset is from the left, center, or right. The value of of t, c, or b determines whether the V-offset is from the top, center, or bottom. As you can see, the offsets can also be negative, essentially moving the inset outside of the larger graphic. The package is available at https://ctan.org/pkg/stackengine, with a companion package for tabbed stacking at https://ctan.org/pkg/tabstackengine. documentclass{article} usepackage{stackengine} usepackage{graphicx} parskip 1em begin{document} defbig{includegraphics[height=4cm]{example-image}} deflittle{includegraphics[height=1.2cm]{example-image}} stackinset{l}{2pt}{t}{5pt}{little}{big} stackinset{l}{25pt}{b}{5pt}{little}{big} stackinset{r}{7pt}{t}{7pt}{little}{big} stackinset{r}{-5pt}{b}{12pt}{little}{big} stackinset{c}{10pt}{c}{25pt}{little}{big} end{document}
