using external flash/eeprom to save bmp in c code?

Hi.

i am using adafruit_ili9341_stm.h (bluepill hardware). this library is not compatible with adafruit_imagereader (or maybe my coding could be have a problem). also the adafruit_imagereader could not be compiled (after adding to sketch and compiling gives "Error compiling for board Generic STM32F103C series.").

so... i want to use external flash/eeprom to save bmp in c code an read it... (just two 320*240 pic)

can anyone help me?
