Does anybody know where I can get small photos (thinking 4x4 or 8x8) printed but on a heavy stock or foam core/board? I want to display photos on table top easels but need a heavier stock than regular photo paper so they don't flutter off when people walk by or the A/C turns on. I looked on-line at Walgreens and Kinkos but did not see what I was looking for. Thanks!
