Well, though I'm using 6 bytes per line ***PER RGB COMPONENT***, I only *NEED* 5 bytes (40 bits). I'm just in "experiment" mode at the moment, not "efficiency" mode. Let's say 5, though. My images are 192 lines deep, so that's 5 (bytes/line) x 3 (RGB planes) x 192 (lines) = 2880 bytes/screen. Ouch!
