Thank you very much. Now it works perfect.
Thank you for your answer. I tried it again in firefox, but still nothing. Explorer and Edge same reason. But when I tried it in chrome, it works perfect. It is enough for me. Thank you very much.
Thank you very much, image is showed in edit window now.
But I have still problem, when I try edit picture. For example I try rotate pics and what I see is only white place. And When I use save, black image is saved. I can restore original pic, it is OK.
Thanks.
