swift change @IBoutlet collection images using the .tag not image

Question

I have setup @iboutlets collection with many images but I want to change the images as a collection and use its tag to chose what image will change but I don't know correct code to change using the tag. I can change a label but get error on images this is how I change image but I need to do it using the image tag

@IBOutlet var Pics: [UIImageView]!

@IBAction func MyAction(_ sender: UIButton) {
        
            Pics.image = (SandDFaults[Fault])
}

I have seen code like I need but this only works on text labels I want to change images here is something like I need

import UIKit

class ViewController: UIViewController {

var outputTagNumber = 0
override func viewDidLoad() {
    super.viewDidLoad()
    
}

@IBOutlet var myLabels: [UILabel]!
@IBAction func myButton(_ sender: UIButton) {
    outputTagNumber = (sender.tag+1)
    let myLabels = view.viewWithTag(outputTagNumber) as! UILabel
    myLabels.text = "Changed this one"
    
    
}

}

How can I do this with images? not text

hope this makes it more clear what I need thanks
