My son gave me some jpg photos to print for him, however it cannot print out. I tried to check it in the photoshop but to no avail. In photoshop I could not see metadata of these photos. I tried to save it into bmp or pdf file, it just could not print out. The photographer may have inserted some code to prevent printing. As no hard copies print out were given to him by the photographer, now he is facing the problem how to print out the photos. I would like to seek you expert advice to solve this problem.
