Photos: Blur or darken background photos to make the quotes pop out more

Right now, the lurid backgrounds make the quotes hard to read. So an option to decrease the brightness of the bg photos will help to outshine the quotes

Dim (reduce brightness) of the background picture / wallpaper a little bit / make it customizable, to make the texts on it (clock, greeting, mantra etc.) optimally more readable. This is not a premium feature, this is basic usability. Thank you.
