I tried your code and found this...

With GTk i was clueless as to why its not working.

With QT i got this error message...
*js: Not allowed to load local resource: file:///tmp/Asymmetricwave2.png*

Can't seem to enable it

And used the above code so have not used any JS as far as i can see, it
must be internal.
