Once you've created a slideshow folder, you can start storing your pictures in it. Any pictures stored in this folder will appear in your slideshow. If you want to display existing pictures, just copy them into this folder. If you don't yet have any pictures, you can take pictures using the iSight camera and store them in the folder.
To display existing digital photographs, first copy them into your slideshow folder:
Click the Finder icon on the Dock. The Finder window appears.
Click the storage device that contains the pictures you want to use. (If your pictures are stored on a compact flash card or flash drive, click the icon that represents that storage device.)
Open the folder that contains the pictures you want to use.
Hold down the
key and click each picture you want to use. (If you want to select all the pictures in that folder, press -A.)Select Edit ▸ Copy. (Depending on the exact number of pictures you copied, the command will read Copy X Items.) This copies your selected pictures (although nothing seems to happen).
Click the Pictures folder in the left pane of the Finder window and double-click your slideshow folder.
Select Edit ▸ Paste Items. Your chosen pictures appear inside the slideshow folder. (Repeat these steps for any additional pictures you want to use in your slideshow.)
If you have existing digital photographs stored in iPhoto, you can copy pictures and store them into your slideshow folder:
Click the iPhoto icon on the Dock. The iPhoto window appears. (If you can't find the iPhoto icon on the Dock, look for the iPhoto icon inside the Applications folder in the Finder window.)
Hold down the
key and click the pictures you want to store in your slideshow folder.Select File ▸ Export. An Export Photos dialog appears.
Choose any options (such as defining the size of the images) and click Export. A second Export Photos dialog appears.
Click your slideshow folder and click OK.
