Since it's still not working, I'd recommend you start checking things
one-by-one to verify they are working as you expect.
* does the gallery work *other* than the description field? Are there any
errors / warnings in the browser console? If so, deal with those before
moving on.
* add a breakpoint inside the 'onslide' handler the documentation provides.
Are things as expected? Are the "text" and "node" variables getting what
you'd expect?
* if everything looks OK but things still don't work, I'd recommend trying
to create a smaller "test case" Rails application that demonstrates the
issue. You'll get significantly better assistance from this list if you can
provide a runnable example of the problem.
