You could use en.radzio.dxp.pl/bitmap_converter/ tool to create the bitmap array. Please make sure you use a binary image(2 level image) and scaled to 96x96 pixels size. Use an image editor software like GIMP to edit or scale the image. If you still face some issue, give details about the problem you face.
I hope you were able to compile and upload Draw Binary Bitmap example from the above wiki.
