PowerShell - Download Images from Web

I had a requirement where I have to export user profile images from MySite 2013 and I end up writing following PowerShell script:

[Reflection.Assembly]::LoadFile( `
'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Web.dll')`
  | out-null 

$FileName = "C:\Temp\ImagesURL.txt";
$Loc = "C:\Temp\Images\"
$ImageName = ""

$wc = New-Object System.Net.WebClient

$content = Get-Content $FileName
foreach ($line in $content)
{
    $Image = $Loc + $line.Substring($line.LastIndexOf("/") + 1)
    $url = $line
    
    Write-Host $url
    Write-Host $Image
    
    $wc.DownloadFile($url, $Image)
    
}

write-host "Finished successfully."

HTTP Request with Javascript

<script type="text/javascript">

var oReq = new ActiveXObject("MSXML2.XMLHTTP.3.0");

function handler()
{
    if (oReq.readyState == 4 /* complete */) {
        if (oReq.status == 200) {
            document.getElementById("myDiv").innerText = oReq.responseText;
        }
    }
}

function SendRequest()
{
    var vURL = "http://IdolApp:12345/data/data.xml";

    if (oReq != null) {
        oReq.open("GET", vURL, true);
        oReq.onreadystatechange = handler;
        oReq.send();
    }
    else {
        window.console.log("AJAX (XMLHTTP) not supported.");
    }
}

</script>
<input type="button" id="btnSubmit" value="Go" onclick="SendRequest()"/>
<br/>
<div id="myDiv" >:o)</div>

Note:
Initialize the oReq with following to make it IE and Chrome compatible:
var oReq;

if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
 oReq=new XMLHttpRequest();
}
else
{// code for IE6, IE5
 oReq=new ActiveXObject("Microsoft.XMLHTTP");
}
