Here are ways to add images or movies to drop zones:
Drag media directly to drop zones on the menu screen.
If a menu has several drop zones, it can be easier to use the drop zone editor, discussed below. To learn how to add media to dynamic drop zones (which are not stationary but move on the menu), see Related Topics below.
To add a movie, drag a movie from the Media pane or another location on your hard disk or a connected server to the drop zone. The drop zone changes to display the first frame of the movie.
To add a slideshow, drag an iPhoto album or an image folder from the Media pane to the drop zone, or drag an image folder from another location on your computer or a connected server. A drop zone slideshow can include up to 99 images, depending on their size.
To add a still image, drag the image from the Media pane or another location on your computer or a connected server to the drop zone.
Use the drop zone editor to see all the drop zones in your project at once and add files to them.
This is especially useful for themes with several drop zones and for themes with dynamic drop zones, which move around the menu. For information on using the drop zone editor, see Related Topics below.
To have iDVD automatically fill all drop zones with images from the media in your DVD, choose Project > Autofill Drop Zones.
iDVD fills each drop zone with files it chooses. You can manually change these files, using any of the methods described above.
