Delete all records in a Picture Library

Hi,

I wrote a simple powershell script to delete all the records in a SharePoint 2007 Picture Library.

$sc = New-Object Microsoft.SharePoint.SPSite($webURL)
$web = $sc.OpenWeb()
$srcList = $web.Lists[$srcListName]

## Loop through the items in the Document Library
$srcItemCnt = 0
foreach($srcItem in $srcList.items)	{
	Write-Host $srcItem["ID"]
	$srcItem.Delete()
}

$web.Dispose()
$sc.Dispose()

But I am getting error "An error occurred while enumerating through a collection: Collection was modified; enumeration operation may not exec
ute.."

Can advise where I am wrong?
