how to make a slide show (question)

This is my question (today)
It's possible make a slideshow with a few jpg's (o bmp) like installshield?
I know the dll bgimage, but how it works?

Somebody can put some examples?

Thaaanksss..👍

Contrib\BgImage\Example.nsi. Shouldn't be too hard to change it so that you can change the picture once in a while.
