I found this nifty resource which outlines how to change the splash screen on a full graphic LCD. He goes into pretty good detail about how to go about it but didn't include much info about making images that would display properly.

The LCD Assistant program works well but it's picky about what images it will render properly so I looked for a solution. I'm not that savvy when it comes to image manipulation so I settled on this program: http://www.getpaint.net/
It's similar to MSPaint but it will show a visible pixel grid so when manipulating a 64X64 image you can work with each pixel and make simple images that will render on the relatively low-res screen.
After getting the image like you want it by drawing with black and white pixels then save it as a .bmp. It must be in a "Monochrome.bmp" for the LCDAssistant to work properly so I ran the image through MSPaint and saved it as monochrome before letting LCDAssistant create the array.
Here's the array for a simple LMR Logobot:

Just replace the bitmap in yer f'ware and be cool like jinx \o/
