In iPhoto, select the photos, albums, or video clips you want to burn to a disc.
Choose File > Export.
In the Export Photos window, click File Export, and then select your options.
For best results, choose JPEG, Maximum, and Full Size. For more information, see Export a photo.
When you’re ready, click Export, and export the photos to a folder on your computer.
When the export is finished, quit iPhoto.
Click the Finder icon in the Dock, and then insert a CD-RW disc or a blank CD-R or DVD-R disc into your drive.
Drag the folder that contains your exported photos to the disc’s icon.
When the files have been copied, choose File > Burn Disc, and then click Burn.
