Digitize your pictures
Today the digital camera is ubiquitous, but photos used to be taken by momentarily exposing something called "film" to light. Yes, film--the ode to photo-sensitive chemical reactions that produced all of the pictures made before 1990 or so. Those images were, and quite often still are, transferred to photo paper and pasted into coffee table albums. Sometimes they were processed into transparent 35mm slides and projected onto white screens for everyone's enjoyment (or boredom, depending).
