+/*
+
+ Esplora TFT Bitmap Logos
+
+ This example for the Arduino TFT screen is for use
+ with an Arduino Esplora.
+
+ This example reads an image file from a micro-SD card
+ and draws it on the screen, at random locations.
+
+ There is a .bmp file included with this sketch.
+ - open the sketch folder (Ctrl-K or Cmd-K)
+ - copy the "arduino.bmp" file to a micro-SD
+ - put the SD into the SD slot of the Arduino LCD module.
+
+ This example code is in the public domain.
