Solution

The path you are saving to is a relative URL. You need to save to a local file path (or full network path).

Try:

string relativePath = @"~\images\"+ i + Path.GetExtension(fu1.FileName);
fu1.SaveAs(Server.MapPath(relativePath));

(Path.GetExtension(string) will handle file extensions that aren't 3 characters too)

Although you should use / in the relative path, not \.

@Guffa Are you sure that makes any difference?

The method may be nice enough to convert the incorrect separators to the correct ones, but there is no reason to rely on that behavior (that might change) when you can just as easily use the correct separators instead.
