This is the first javascript I have ever done and tbh I feel its too advanced for a complete noob.

I am suppose to try to display 5 images out of jpgs 1-9.

All 5 displayed are suppose to be random. I have no idea how to do it and been going through the book trying different things for like a hour now.

highlighted the parts I am working on in blue
