You may use the z coordinate of your flat curves to manage overlays,

c  =  e.children;

xstring(0,-1,"$\scalebox{1}{\includegraphics{http://www.cnrs.fr/fr/z-tools/newune/themes/CNRSTheme/images/logocnrs.png}}$";)
c.data(:,3)  =  0.1;  // <<<==== HERE
c.thickness  =  2;You may then tune the scalebox factor. Actually, like with an 
uicontrol(style="image"), the imported image is inlaid and is not 
resized accordingly with the embedding graphical figure. HTH Samuel

Thank you  for sharing these very good methods. It opens a lot of new 
possibilities.

The way I want to use images in figure I  find it better to modify your 
script with newaxis() before plotting. This makes the picture stay  
while zooming for instance:

clf
xstring(0,0,"$\scalebox{.3}{\includegraphics{http://photos.marinetraffic.com/ais/showphoto.aspx?photoid=445734}}$";); 
g=get("current_figure"); g.figure_size=[345,575]; b=newaxes(); b.filled 
= "off"; x  =  linspace(0,20,200);
plot(x,sin(x))

By the way it would have been interesting to see an example with 
uicontrol(style="image")  that you mention. I could never get that right.
