@arthurdent: I don't know why you get the errors. This module was not tested on a lot of different sites, but so far it works fine on the sites I made. I posted it just as an example of how I solved the problem of adding a banner rotator...
@Howard: I will make a note in the README file about the DataObjectManager module.
Yes. You have to add some images (in the tab Slides of the RotatorPage) and publish the RotatorPage.
Then view the sourcecode of this page (in your browser) and copy the code between BEGIN CODE and EINDE CODE and paste it in the TinyMCE editor of another page (use the HTML button)
