image upload in C#

I'm trying to upload image into SQL server database.
What's important is that i'm not really uploading image itself, but path to the location of the picture
I'll save the picture in designated location (in this case let's say it's c:\images\), and have imageURL
saved like \images\picture1.jpg

I'd like to set a limit so that people don't upload anything but jpg, bmp, gif, png

I'll post up what I have and please help ASAP code.txt code.txt

I missed one property in

string extension = Path.GetExtension(fileUpload.PostedFile);

Replace the above with below :

string extension = Path.GetExtension(fileUpload.PostedFile.FileName);

i did. Problem is now that it's not getting any file even though i upload it.
It does not even show any message
I already uploaded aspx file up there and I'm going to attach code snippet for my behind code.
it seems like the it has no file even though I choose the file.
if (fileUpload.PostedFile.ContentLength > 0)
        {
            string extension = Path.GetExtension(fileUpload.PostedFile.FileName);
            if (extension == ".jpg" || extension == ".jpeg" || extension == ".jpeg" || extension == ".png" || extension == ".bmp" || extension == ".gif")
            {
                try
                {
                    string fileName = System.IO.Path.GetFileName(fileUpload.PostedFile.FileName);
                    string savePath = "c:\\images\\";
                    fileUpload.PostedFile.SaveAs(savePath);
                    Session["filename"] = fileName;
                    Response.Write("File Uploaded");
                }
                catch (Exception ex)
                {
                    Response.Write(ex.Message);
                }
            }
            else
            {
                Response.Write("Please upload jpg/jpeg, bmp, gif, png file only");
            }
        }
            
        else
        {
            Response.Write("You have no file.");
        }

Now.. I think there is something wrong with this part


try
                {
                    string fileName = System.IO.Path.GetFileName(FileUpload1.PostedFile.FileName);
                    string savePath = "c:\\images\\";
                    FileUpload1.PostedFile.SaveAs(savePath);
                    Session["filename"] = fileName;
                    Response.Write("File Uploaded");
                }
