// To use, add a parameter to the widget with a format of: image.png|padding-top|text-color
// The image should be placed in the iCloud Scriptable folder (case-sensitive).

// The text color parameter should be a hex value.

// For example, to use the image bkg_fall.PNG with a padding of 40 and a text color of red,
// the parameter should be typed as: bkg_fall.png|40|#ff0000

// All parameters are required and separated with "|"

// Parameters allow different settings for multiple widget instances.
