$titleOrig = 'File:Tour Eiffel Wikimedia Commons.jpg'
$pref = 'https://upload.wikimedia.org/wikipedia/commons/thumb'
$thumbSize = 200
$title = $titleOrig.Substring(5) -replace ' ','_'
$hash = ([System.BitConverter]::ToString($md5.ComputeHash($utf8.GetBytes($title)))).replace("-","").ToLower()
$pref,$hash.Substring(0,1),$hash.Substring(0,2),$title,"${thumbSize}px-$title" -join '/'
