Modification of slider module (or other module).
For a number of different purposes it would be quite useable to have the option
of "instant switching" between pictures that lays in layers in top of each other.
It should also be possible to do this using a "push buttom" with some text,
lets say "picture one" og "state one".
This could be used for the purpose of technical training and also other purposes.
Excample:
There is an electric cirquit with no elecrric power on it. You can see
a picture of the cirquit in the condition "no power".
