Hi @steven,

Pretty much everything listed you need by @glv.

Maybe some meta description…

```auto
On start
    Create an array with available images.
    Initialize variables for currentImageindex and nextUpdateTime with suitable values 

On draw loop
    check if currentTime >= nextUpdateTime
    If true
        increment currentImageindex mod size of image array
        add interval to nextUpdateTime
    set background using currentImageIndex on available images

```

Cheers
