STM32f7 discovery SD Card

Hi

I'm working on a STM32f7 cardboard and I use the library from the example programme of the mbed compiler. I'm trying to use the stm32746g_discovery_sd.h with my sd card. I managed to make this code to verify is the SD card is present at the start on of the cardboard (sorry it's in French, I'm French):

void Detection_Carte_SD(void)//Detection presence carte SD
{
    CARTE_SD = BSP_SD_IsDetected();
    if(CARTE_SD == 1) {
        Etat_Init((char *)"SD PRESENT");
    } else {
        Etat_Init((char *)"SD ABSENT");
    }
}

But now I don't know how I read picture on my SD card. to I need to put it on FAT format?

I tried to use the "SDFileSystm_HelloWorld" library but didn't work like this guy :

And I'm not sure we have the same pin association.

So can you explain me how we do taht? thanks
