treat it like a document, place it in an anchor tag. You will obviously need two of them, one for each image.

Thanks for replying matt.I did as you suggested

I tried using an anchor like this giving path using 'http' and mentioning the drive::

<a href="http://server_name/images/HIGH_RES_IMAGE_NAME.gif">Download High resolution image</a>

<a href="f:/images/HIGH_RES_IMAGE_NAME.gif">Download High resolution image</a>

With that, on click of hyperlink the image gets opened up in same browser window and doesnot pop up for download.

You may want to take a look at this FAQ: http://Imar.Spaanjaars.Com/QuickDocId.aspx?QUICKDOC=189

It explains how to force the Save As dialog with an ASP page...

Hello,

Thanks a lot,the article was good and very useful.I have a parent page which open the page in new window focing save as dialog box.After the user has saved the file the window remain closed.How to close the window.As if I write javascript as mentioned below it does not goes to the browser.

<%
    FileName = request.querystring("Filename")
    FullFileName = "F:/inetpub/wwwroot/download/"&FileName
    Response.ContentType = "application/x-unknown"
    Response.Addheader "Content-Disposition", "attachment; filename=" & chr(34) & FileName & chr(34)
    Response.Binarywrite GetBinaryFile(FullFileName)

    Function GetBinaryFile(ByRef FileSpec)
        Const adTypeBinary = 1
        Dim objStream
        Set objStream = Server.Createobject("ADODB.Stream")
        objStream.Open()
        objStream.Type = adTypeBinary
        objStream.LoadFromFile FileSpec
        GetBinaryFile = objStream.Read()

        Set objStream = Nothing
    End Function
%>

<html>
<head>
<script language="Javascript">
function cls()
{
window.close();

}

</script>
</head>
<body onload=cls()>

</body>
</html>

Thanks,
Priti

further to my reply if i try to close the child window through javascript in parent window then the save as dialog box does not appear and the child window gets closed without doing anything.

Thanks,
Priti

You don't need an additional window. Just link to the page directly. The browser will see you're downloading a file and leave the current page in tact.

So, something like:

<a href="DownloadFile.asp?Id=123">Download</a>

would work fine. It shows the download dialog as a separate dialog, without affecting the page that has the link.

Does this help?

I have made similar code, however, after the force-download dialog appeared, is it possible to detect if user press "Cancel" button?.
