How to create randomised strip backgrounds???????

I’ve seen that this question has been asked a few times on the forums, but the solutions I’ve tried haven’t worked. Can anyone create a code for me to use that A. Takes its data from a dataset, B.I can attach to a strip and C. When refreshes, displays a different image FROM that database?

I am a filmmaker, and so not a very good coder; and I’ve become increasingly frustrated at trying to figure out these other solutions and NONE of my editing of their coding suggestions have worked.

If anyone can help it would be greatly appreciated.
