{{bloc-etroit|text=There is a built in microSD card slot into the shield, and we can use that to load bitmap images! You will need a microSD card formatted FAT16 or FAT32 (they almost always are by default).
Its really easy to draw bitmaps. Lets start by downloading this image of pretty flowers (pix by johngineer)}}

Copy '''purple.bmp''' into the base directory of a microSD card and insert it into the microSD socket in the shield. Now upload the '''file->examples->Adafruit_ILI9341->spitftbitmap''' example to your Arduino + shield. You will see the flowers appear!

To make new bitmaps, make sure they are less than 240 by 320 pixels and save them in '''24-bit BMP format'''! They must be in 24-bit format, even if they are not 24-bit color as that is the easiest format for the Arduino. You can rotate images using the '''setRotation()''' procedure
You can draw as many images as you want - dont forget the names must be less than 8 characters long. Just copy the BMP drawing routines below loop() and call
bmpDraw(bmpfilename, x, y);
For each bitmap. They can be smaller than 320x240 and placed in any location on the screen.
