Assuming your output device knows how to render BMPs, then you can just treat the BMP as a chunk of data. You will need to write a quick little program for a PC to read in the BMP file one byte at a time, then generate an ASCII output file containing a C array declaration prefilled with the data. You then include the generated file in your project.
If your output device does not know how to render BMPs, then you will probably need to find out the BMP file format and work out how to convert it to what you need. Then you can use the same method I just described except transforming the data as needed.
