The partially displayed image most probably is a result from the configured size of the RadRotator control. Note that if you want to show one or more rotator items per view without showing parts of another views, you need to set fixed size for the rotator and its items via the properties Width
You can check the following help article for more information and examples for configuring the rotator: http://www.telerik.com/help/aspnet-ajax/rotator-configuration.html
If you are still having difficulties with setting the size of the rotator, please open a support ticket and send a fully runnable sample that isolates the problem so that I can inspect it locally and provide a more to the point answer.
