I have been trying to get some custom prints to work. They are pics from my camera I renamed them and made them .PNGs. I thing i have put them in the right folder which I think is 2x2 in printIcons and 2x2 in prints but when I start blockland a try and print them on to a 2x2 printable there print Icons are blank and there prints are blank. What do i do to fix this.
