Dear Thomas,
I tested making my simpleslides module SsuWave by modifying
simpleslides-s-Rounded.tex
(1) I just replaced MP figures for horizontal and title with some figures as
follows for test :
\defineoverlay
[simpleslides:background:horizontal]
% [\useMPgraphic{simpleslides:MP:horizontal

\defineoverlay

[{\externalfigure[/Users/graph/Documents/figures/background/ssuwave1][]}]
And I would advice to have a look at the directory key of
\setupexternalfigures. It is almost always a mistake to have a hard
coded path in the code.

Is there a way to do such a job?
2. Is it possible to use my own figure as a background under the simpleslide
module?
-- Example--
\usemodule[simpleslides][style=HorizontalStripes,font=]
\defineoverlay[yellow-spring][{\externalfigure[./background/yellowspring][width=\paperwidth

\defineoverlay[yellow-spring][{\externalfigure

less code:
\defineoverlay
[BackgroundImage]
[\overlayfigure{Makeup/Images/Background.png}]
, the following
on second page,
\setupbackgrounds[page][background=BackgroundImage]
. But this does not work properly. What ends up happening is the cover
image is displayed correctly, but every page after that just has a blank
white background.
