how to automatically change the background image every month ?

[stephaud13]

Hi everyone !
There is a way to change every month the background image of a section, automatically i mean ?
Something like a script (i guess) that pick an image sequentially from a folder, and changes monthly the background image of a specific section...
It would be great that automatically the BG image changes monthly without the need to manually change it from the layout.

Thanks for your help !
