Randomisation of images in a condition

OS (e.g. Win10): Win10
PsychoPy version (e.g. 1.84.x): 1.83.04
Standard Standalone? (y/n) : y
What are you trying to achieve?:
Sorry, I am very new to this and I think I’m biting more than I can chew here. I’m trying to create an experiment that displays either 2,4 or 6 images in one screen randomly from a set of images that I have (can be repeated). Each image will possess a value (they are all named either -4, -2, 0, 2, 4) that I would like to be able to use to calculate a certain data, that is to say I would like for the images chosen to be also displayed in some way to me.
What did you try to make it work?:
What specifically went wrong when you tried that?:

There doesn’t actually seem to be a question here?
