/* Create C arrays from jpeg images using this online tool:
http://tomeko.net/online_tools/file_to_hex.php?lang=en
If needed, first resize and crop to an appropriate width and height
to suit your display with an image editing program such as GIMP, IrfanView.
You can also change the image "quality" to reduce the file size.
Paste the array into a new tab, top and tail the array from the
tool to look like the one below with:
#include <pgmspace.h>
const uint8_t img_name[] PROGMEM = { //start with thisline
// 8bit array contents
}; // end with this line
No forget to change the name of the array 'img_name'
*/
