Hello there, scbullard.

The online iPhoto Help menu provides some great information for changing settings on your slideshows, including the length of time a slide plays:

If you want to apple the change for the entire slideshow:

To change settings for an entire slideshow:

• Select the slideshow in the Source list, click the Settings button in the toolbar, and then click All Slides.
• While a slideshow is playing, move the pointer to make the slideshow controls appear, and then click the Settings button:
1. Do one of the following:
   • To set the length of time each slide appears, select “Play each slide for a minimum of __ seconds,” and click the arrows to increase or decrease the number of seconds.
   • To play the slideshow as long as the music plays, select “Fit slideshow to music.”
2. To change the effect between slides, select the Transition checkbox, and then do one or both of the following:
   • Choose a transition from the pop-up menu. For some transitions, you can change the direction in which the effect occurs by clicking the arrows.
   • To change how long the transition lasts, drag the Speed slider.
   Tip: If transitions play too slowly, try decreasing your screen resolution (choose Apple menu > System Preferences, and then click Displays). Very large photos might also transition slowly; try changing the photo’s size (see Export a photo).
3. If you wish, specify additional slideshow settings:
• To make each slide’s title, description, place, or date appear, select the Show Caption checkbox, and then choose an item from the pop-up menu.
• To display slides in random order, select “Shuffle slide order.” If you don’t see this option, play the slideshow, move the pointer to make the slideshow controls appear, and then click the Settings button.
• To automatically restart the slideshow when it’s over, select “Repeat slideshow.”
• To prevent black borders from appearing on photos cropped to an aspect ratio that doesn’t match the display’s, select “Scale photos to fill screen.”
• Choose an option from the Aspect Ratio pop-up menu, depending on where you’ll play the slideshow. If you don’t see this option, press the Escape key on your keyboard, and then click the Settings button in the toolbar.

If you want to make the change to individual slides:

To change settings for an individual slide:

Before you change settings for specific slides, it’s best to specify the settings for the slideshow as a whole. If you specify settings for individual slides and then change options for the whole slideshow, the slideshow settings might override the individual settings.

1. Select the slideshow in the Source list, and then select a slide in the photo browser at the top of the iPhoto window.
2. Click the Settings button in the toolbar, and then click This Slide at the top of the Slideshow Settings window.
3. Do any of the following (some options aren’t available for every slideshow theme):
• To add an effect such as a sepia tint, click one of the effect thumbnails. To turn the effect off, click the thumbnail again.
• To change the length of time the slide plays, select the “Play this slide for” checkbox and click the arrows to increase or decrease the number of seconds.
• To change the slide’s transition effect, select the Transition checkbox and choose an option from the Transition pop-up menu. To change the transition’s duration, drag the Speed slider. For some transitions, you can also change the effect’s direction by clicking an arrow on the directional button.

Tip: To see the transition, click the Preview photo.

• To customize the slide’s pan and zoom effect, select the Ken Burns checkbox. For more information, see the task below.
