Let's See Your Boot Opening Screens + (Tutorial)

You can get awful creative like this. I've done my XP machine and a couple phones.
Curious, anyone try gif format? Also a TIF format should work given no compression.
'paint' will not work becaus the file headder is different. It must be converted to bitmap, and specifically 24 bit color.
Pixel height and width are specific. I think you can reduce it but it would be smaller on such displays.

Graphics of the correct size in the .bmp format are the only graphics the scanner will recognize when it boots up, it will ignore all other formats and sizes.

MS Paint will work as well as any other graphics editor for creating opening graphics as long as the size is set to the correct parameters and "saved as" a 24 bit .bmp file named "opening.bmp".
