+.SYNOPSIS
+    Azure Automatic Cleanup Script for Unused Images.
+
+.DESCRIPTION
+    This script creates a new Azure Resource Group with the Azure PowerShell.
+    The script uses the following Azure PowerShell command:
+    New-AzResourceGroup -Name $AzResourceGroup -Location $AzLocation
+
+.PARAMETER DryRun
+    It allows you to simulate the execution of a script or command without actually making any changes to the system.
+
+.PARAMETER ResourceGroup
+    Defines the Azure Resource Group that a particular command or operation should target.
+
+.PARAMETER ImageId
+    Defines the unique identifier of an image resource in Azure. 
+
+.EXAMPLE
+    param(
+    [string]$ResourceGroup,      # Name of the target resource group
+    [string]$ImageId,            # Unique ID of the image to check or remove
+    [switch]$DryRun              # Simulate the process without making changes
+)
