Splash screen images files must be 24-bit BMP files of size 240x304 or 240x300 pixels. The current splash screen image is the one stored in the root directory of the SD card and named "splash.bmp". Images stored in the SPLASH folder can be made the current splash image by clicking on the BMP file in File Manager to view it, and then pressing the Right button (this will cause the file to be copied to the root folder and renamed "splash.bmp", overwriting any existing "splash.bmp" file in that location). In order for the current splash screen to appear at power up, the "Show splash screen" option must also be enabled under Settings->UserInterface.
