php - Saving black and white image in the database -


i need save black , white images in database. sequences of bits - either white or black. efficient way store them in database?

my idea save dimensions , put them binary code resolved 1011000111 etc. images can quite big. saving them image files doesn't make sense, because i'll need access pixel data on regular basis , don't want put color information. said black , white, can yellow , pink too.

what column type should use , how can encode , decode images?
