I finally got around to releasing my simple slideshow sketch for the Cheap Yellow Display (folk kept mailing me after stumbling onto my secret in-progress web page, via search engines, so...).
I finished the page, put up a zip. It's all yours.
It's designed to be simple to operate; put some JPEG files on an SD card and away you go. With full touch and serial control.
It's been a while since I updated my Arduino, so if there are any issues, let me know.
Full details here..

Enjoy!
