Can i make a random image from other images being referenced

I'm making a website using wix and I have set up 7 groups of png images with varying numbers of png images in each group. by group I mean I have imported them to a blank page and put all pngs together and used the group function. how can I make a button that will randomly select one png from each group and layer them on top of each other in order e.g background layer 0, body layer 1, shirts layer 2, eyes layer 3, nose layer 4, mouth layer 5, hair layer 6, accessories layer 7 and save them into a gallery on the website? and would it be possible to make 10 or 100 output images each time someone clicks generate?

I know you can enter or rather embed code in wix for more in depth functions like this
