The author (m0ns00n) asked me to clarify something:
"Reply to the news post of Lunapaint that the images shown in the screenshots are photos imported as raw64. They were taken randomly from the web and converted with image2raw, the small linux command line app I made which you can download on the lunapaint website [download section].
The image import functionality which can read png, jpg etc is not available in Lunapaint yet and won't be before v0.3 most probably.
Right now Lunapaint only reads .lun and raw64 (64-bit raw data)".
