Please help me upload a png image from the SD card on ESP32s3

How to

Hello everyone,
I would like to import a png image from the sd card into the button “ui_ImgButton1” so that it changes the original image when the button is pressed.
This is my code:

void ui_Screen1_screen_init(void){
    ui_Screen1 = lv_obj_create(NULL);
    lv_obj_clear_flag(ui_Screen1, LV_OBJ_FLAG_SCROLLABLE);      
    ui_ImgButton1 = lv_imgbtn_create(ui_Screen1);
    lv_imgbtn_set_src(ui_ImgButton1, LV_IMGBTN_STATE_RELEASED, NULL, &ui_img_bt_red_png, NULL);
    
    lv_imgbtn_set_src(ui_ImgButton1, LV_IMGBTN_STATE_PRESSED, NULL, "S:/bt_yw.png", NULL);

    lv_obj_set_height(ui_ImgButton1, 50);
    lv_obj_set_width(ui_ImgButton1, LV_SIZE_CONTENT);  
    lv_obj_set_x(ui_ImgButton1, 4);
    lv_obj_set_y(ui_ImgButton1, -4);
    lv_obj_set_align(ui_ImgButton1, LV_ALIGN_CENTER);
}

Where am I wrong?
Can anyone advise me how to do it?
Thanks.

The problem has been fixed, it’s due to my inexperience with Arduino programming.
Everything works fine, with sd very slow but with Ffat better.
So all ok, sorry for opening the topic.
Thanks!
