Yes! I did this for a number of years by using a copier. I just copied my photos, (final project in black and white). Lined them up on a page. some months may have had one photo, blown up to the size of full page, and some months had more than one photo in it.
I did theme calanders. Family- grandchildren, or for my mom, her children.
I even did one for my sister of photos I had taken of her husband at the years family gatherings, silly expressions, and called it her 'he man' calander.
The month part can be done on the computer easily. You can copy on paper that is double in size, staple together, and fold over so the final size is regular size 8x11.
