I believe it's not recognizing it because most browsers don't support it.
My recommendation would be to convert to jpg or png format

Ditto on the other post.

Here are some options as I see them:

1. Force your users to install some thirdparty tool. (Not a good option,
but an option).
2. Convert to gif or jpg. If you have a bitonal tiff, then use gif. If
you have alot/lotta colors, use jpg.
3. Buy a third party tool like:
http://www.atalasoft.com/ajaxviewer/

#2 is your cheapest/least client dependacies. However, you have to pay the
price each time you serve the file up.

Here's a sample script that will work as showimage.aspx?
image=file.tiff, where file.tiff is a name of the file in the root

<%@ Page Language="C#" %>
<script runat="server">
void Page_Load(Object sender, EventArgs e)
{
string imageLocation = Server.MapPath(Request.QueryString["image"]);
System.Drawing.Bitmap origBitmap = new
System.Drawing.Bitmap(imageLocation);
System.Drawing.Bitmap outputImage = new
System.Drawing.Bitmap(origBitmap);
System.Drawing.Imaging.ImageFormat outputFormat =
System.Drawing.Imaging.ImageFormat.Jpeg;
outputImage.Save(Response.OutputStream, outputFormat);
outputImage.Dispose();
origBitmap.Dispose();
}
</script>

as you can see it converts an image into Jpeg. Note, that the
System.Drawing.Bitmap object has a problem to load some TIF files.
Some work and some don't ("Parameter is not valid" error is thrown).
As I see it can be a problem of the format. For example, for files
with no compression, or in LZW it would work, and ZIP is not working.

Hope it helps
