Me revoilà, alors voici le code fonctionnel pour l'affichage des 4 .BMP avec les bonnes bibliotheques, merci de votre aide
/***********************************************************************************
*This program is a demo of how to display a bmp picture from SD card
*This demo was made for LCD modules with 8bit or 16bit data port.
*This program requires the the LCDKIWI library.
* File : show_bmp_picture.ino
* Hardware Environment: Arduino UNO
* Build Environment : Arduino
*Set the pins to the correct ones for your development shield or breakout board.
*This demo use the BREAKOUT BOARD only and use these 8bit data lines to the LCD,
*pin usage as follow:
* LCD_CS LCD_CD LCD_WR LCD_RD LCD_RST SD_SS SD_DI SD_DO SD_SCK
* Arduino Uno A3 A2 A1 A0 A4 10 11 12 13
* LCD_D0 LCD_D1 LCD_D2 LCD_D3 LCD_D4 LCD_D5 LCD_D6 LCD_D7
* Arduino Uno 8 9 2 3 4 5 6 7
*Remember to set the pins to suit your display module!

, j'ai reussi tant bien que mal à lire des fichiers en .bmp d 'une carte SD de mon ecran TFT 3.5 pouces, mais cela a été avec les bonnes bibliothèques.
Certains écrans n'ont pas de lecteur SD.
, je vais continuer à me debrouiller par moi même mais ce n'est pas une mince affaire surtout que le code n'est pas à ma portée.
