    Please refer MP3 player sample code provided with bluescreen kit along with Bluescreen_Manual.

    For Image Display (From Prog Mem) ---->
    First convert the into hex file.
    Then inclue image file as .h in you program.
    You can use ScrObjInit(MP3ScreenInit) function to display image.

    MP3ScreenInit() is another function in which you initialise structure object so_obj.
    This structure contains functions related to each image.In that structure draw() function is present which actually display image on LCD.
    Please pass base address of array of image hex file to TSLCDShowPic2() function present in draw() function.
