Errors on uploading file images to server
<p>I want to upload file images to server but I get errors. I can't identify the problem</p>

<p>I use this line of code to upload using asp.net <code>fileupload</code> control  </p>

<pre><code>FileUpload1.PostedFile.SaveAs(Server.MapPath("products_images/")
                                          + FileUpload1.PostedFile.FileName);
</code></pre>
