Unrecognized configuration section httpHandlers in Web.Config with Microsoft Visual Web Developer 2010 Express

I am in need of some help with an error message I get with Microsoft Visual Web Developer 2010 Express.

I would like to create a gallery for my site so I downloaded the NotesForGallery from codeplex. I have added the reference into the project like it told me to in the installation instructions. The instructions then say

Register the ThumbnailHandler in the Web.Config file (httpHandlers section):

<httpHandlers>
…
<add verb="*" path="ThumbnailHandler.ashx" type="NotesFor.ThumbnailHandler, NotesForGallery"/>
…
</httpHandlers> 

So I open the web.config file in my solution and I add it in. When I try and start the website (clicking the play button in Web Developer) I get the error message:

Unrecognized configuration section httpHandlers.

The complete list of errors I get are:

Message 1 Could not find schema information for the element 'httpHandlers'. C:\Documents and Settings\adam\My Documents\Visual Studio 2010\WebSites\FatBoyFudge\Web.config 38 4 C:...\FatBoyFudge\ Message 2 Could not find schema information for the element 'add'.

The project I created was a website if that helps any.

The complete web.config is as follows:

<configuration>
    <connectionStrings>
        <add name="ApplicationServices" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient"/>

                <add name="AspNetWindowsTokenRoleProvider" type="System.Web.Security.WindowsTokenRoleProvider" applicationName="/"/>
            </providers>

        <modules runAllManagedModulesForAllRequests="true"/>
    </system.webServer>
  <httpHandlers>
      <add verb="*" path="ThumbnailHandler.ashx" type="NotesFor.ThumbnailHandler, NotesForGallery"/>
  </httpHandlers>
</configuration>

Any help you could give me would be handy because I'm not sure what I am doing wrong

Put your httpHandlers in the system.web section.

Change the app pool to use "integrate mode' instead of 'classic'
