Hi Courtney,
The show you mention, which featured guests' pictures, was part of Disney's "Let the Memories Begin" promotion in 2012 and has ended
The newest light projection show on Cinderella Castle premiered in November and is called
"Celebrate the Magic." It is pretty spectacular, but does not feature photos of guests.
Before your visit, you might want to check out the details of this year's promotion,
"Limited Time Magic." Throughout 2013, Disney will feature special events, products, characters or other surprises for a sport period of time.
For example, characters that are seldom seen may make appearances for one week only; the Dapper Days barbershop quartet at Magic Kingdom will sing songs by boy bands such as the Backstreet Boys for a while; or villains will host a special party on a Friday the 13th.
I hope you can participate in one of these special treats during your visit to make it even more magicall. Please let me know if I can answer any other questions for you.
