All you need is CD cases (It depends on how big your picture will be), a computer (To edit your picture), a scissor or paper cutter, double-sided tape, and of course, your picture (I suggest you to use a high-resolution picture).

Old CD cases. In your computer, divide your image into some 13.8 x 11.75 cm square. Cut and paste each square into a separate file. Print them and trim off any white space. Then slip each segment, image side up, into a CD case and close it. Repeat until every photo sits inside a case.
