Unihiker K10: Arduino code for time-lapse camera

I bought a Unihiker K10 several months ago. I just finished an Arduino code for using the K10 as a time-lapse camera that I'd like to share with the community. It features options for either direct streaming to the display screen, or time-lapse capture of jpeg images to the SD card. The captured images can be in 5 different pixel sizes ranging from 240x320 to  1280x1024. The time interval can be set from 1 second to 24 hours. The Arduino code is on Github at:

I would appreciate any comments you have, either here or on the Github repository.
