Photographic memories are good for two things: memorizing the periodic table for chemistry tests and memorizing your name so no one else takes credit for your chemistry test. Jog memories with today's Groupon: for $50, you get a personalized photo slideshow from Prestigious Films (a $250 value). The film studio's carefully crafted videos capture vivid images and commemorate cherished memories. Decommission dusty photo albums with a fully mastered DVD storyboard collage, enabling easy views of wedding portraits and sentimental snapshots of your pet tortoise taken before he stopped posing for photos. Keepsake collectors can mail Prestigious Films a CD with up to 150 photos and any song of their choice, and the staff of picture preservationists will format the images, insert professional transitions, and jazz it up with a soundtrack. For $9.99, score a duplicate DVD to share memories with friends, family, and amiable amnesiacs.
