Thank you so much ! It works as I want it!

Could you explain why you need it in SRAM?

If I use dozens of pages with the same layout and multiple images per page, the code will be cleaner.

Kind of like this:

// different images are stored with PROGMEM
const size_t aFlashBitmapSize = sizeof aFlashBitmap;

uint8_t actualLogo[aFlashBitmapSize];

int brand =1;
---------
if(brand==1){
     memcpy_P(actualLogo, logoA, aFlashBitmapSize);
     memcpy_P(actualLogo2, logoB, aFlashBitmapSize);
     //etc
}

tft.drawBitmap(30, 30,  actualLogo1, 64, 64, BLACK,  WHITE);
tft.drawBitmap(30, 150,  actualLogo2, 64, 64, BLACK,  WHITE);
//etc
