Throwing a surprise party for a friends 30th? (or 40th or 50th...) Why not get together the best photos from the night and have a DVD slideshow produced to remember the occasion?
Another popular alternative is to have a slideshow produced using photos of the birthday boy or girl as they were growing up. This makes for a unique and personal gift that is sure to be treasured for years to come, and could even make a great centre point for the party itself!
