Graphic lcd jhd12864e not showing any image

Hi everyone. I have connected a 128x64 graphic lcd with my arduino and used the "u8g" library. I have used a software to convert the bitmap image to hex array. But when I plot the bitmap on the GLCD it doesn't show. Can anyone help me? The image is a 128x64 bitmap.

#include "U8glib.h"

Before jumping into the deep end, trying to display a custom bitmap, have you tried the examples that come with the library? Rule out hardware issues, first.
