Imovie and it's "themes" help

I am making a slideshow in Imovie, and I love the Roadtrip theme, I am using the newest Imovie and with the roadtrip theme all the pictures just zoom in, how can i avoid this w/o loosing the roadtrip theme?

I have never used iMovie for something like this, but I believe that there is a Button for "Ken Burns Effect" which is the effect you are describing, see if you can uncheck that box and you should have non zooming pictures while keeping your theme.

where can i find this ken burns button?

Okay, so I found the button, but can I remove the effect on a "themed" sequence without starting over?

If you don't want the pan and zoom effect applied to an image, make sure you deselect the Ken Burns Effect checkbox in the Photo Settings window before you add the photo to your movie.

If you add motion to a photograph in your movie and then change your mind, you can remove the pan and zoom from it.

To remove the pan and zoom effect from a photo in your movie:

Select the image in the clip viewer or timeline viewer.
Click the Media button, click Photos at the top of the Media pane, and then click Show Photo Settings.
In the Photo Settings window, deselect the Ken Burns Effect checkbox.
Click Apply.

So to answer your question, no - you shouldn't to start over from scratch.
