Turn a case statement into a function

I have a case statement (from an earlier post - thank you) that works. I was wondering if it could be edited and change into a function instead. I think it would be cleaner. The variable is set in the Form Properties (pCounterA).

switch (pCounterA.value)
{
    case "1":
    profileA__1image.rawValue = profileA_1image.value.image.value;
    pCounterA.value = "2";
    break;
   
    case "2":
    profileA__1image.rawValue = profileA_2image.value.image.value;
    pCounterA.value = "3";
    break;
   
    case "3":
    profileA__1image.rawValue = profileA_3image.value.image.value;
    pCounterA.value = "4";
    break;
   
    case "4":
    profileA__1image.rawValue = profileA_4image.value.image.value;
    pCounterA.value = "5";
    break;
   
    case "5":
    profileA__1image.rawValue = profileA_5image.value.image.value;
    pCounterA.value = "1"; // loops back to the first image
    break;
}
