with two other plug-ins: the Image Viewer plug-in and the Multimedia plug-in. The Image
Viewer plug-in lets you view Adobe PDF multimedia slideshows and eCards (personal
greetings sent via email) that were created with Adobe Photoshop Album. The Multimedia
plug-in lets you play sounds and movies. (See
