I was at a wedding where the bride and groom had made paper cubes and glued square cut pictures to them to make photocubes.
They had put 3 or 4 different ones at each table, childhood pictures and such.
As a web developer, I knew there was an easier way to make these and created the site http://easyphotocube.com where a bride and groom can print out a paper pattern with their pictures already printed on the sides of the photo cobe, ready to cut out and assemble.
Examples can be seen here: http://easyphotocube.com/cubes/A20090321F0584019D1D2C3A7A774AD60B95D681C.html

By the way...the site is FREE!
