I write a script to genreate rand string and image it with imagejpeg, the picture(0.jpg-9.jpg)'s color is red and the picture(a.jpg-f.jpg)'s color is blue, but when I test it I found sometime the color of new image will make some mistake, such as red digital picture became white-blue and the blue digital picture became white-red.
