PNG Image does not show up

      lv_obj_t *obj = lv_img_create(parent_obj);
          objects.transparent_test2 = obj;
           lv_obj_set_pos(obj, 100, 5);
           lv_obj_set_size(obj, LV_SIZE_CONTENT, LV_SIZE_CONTENT);
          lv_img_set_src(obj, "S:/PNG/wink.png");

I use LVGL 8.4 and the cheap yellow display
This is my Code in screen.c
