A portfolio photo compact disc visual/audio display system for displaying images and any associated audio stored on a photo compact disc. The system includes first and second photo compact disc players for playing the photo compact disc and a control device. Each photo compact disc player has an output representative of one image and any associated audio stored on the photo compact disc. The control device has a display output and an internal switch coupled to the outputs of the first and second photo compact disc players and to the display output. The control device is able to control the switch to selectively change the display output between the images and any associated audio from the outputs of the first and second photo compact disc players without a noticeable transitional delay. Additionally, the control device is able to queue the first or second photo compact disc player not selected by the control device for connection to the display output to the next image and any associated audio on the photo compact disc for display. The system monitors the audio output by the first and second photo compact disc players and an internal timer to control when the switch is made. With the system, a viewer will not notice a transitional delay between displayed images. Additionally, the visual images will always be synchronized with the audio output.
