If you are regularly creating images on a schedule, you may wish to clear out the older ones. This script will remove images older than a given date, as long as they don't have clone databases dependent on them (in which case warn in the output).

Connect-SqlClone -ServerUrl 'http://sql-clone.example.com:14145'
 
$imageTimeToLiveDays = 7;
 
$oldImages = Get-SqlCloneImage | Where-Object {$_.CreatedDate -le (Get-Date).AddDays(0-$imageTimeToLiveDays)}
 
foreach ($image in $oldImages)
{
    $clones = Get-SqlClone -Image $image
    
    if (!($clones -eq $null))
    {
        "Will not remove image {0} because it has {1} dependent clone(s)." -f $image.Name, $clones.Count
    }
    else
    {
        Remove-SqlCloneImage -Image $image
        "Removed image {0}." -f $image.Name
    }
}
