HttpHandler Not Working

I've never setup a HttpHandler before. What've I done isn't working. Can someone help? The following is what I've done.

1. Created a ClassLibrary project called ImageHandler.

Code:

---

Imports System
Imports System.Web
Imports System.Drawing
Imports System.Drawing.Imaging
Imports System.IO

Public Class ImageHandler
    Implements IHttpHandler

    Public ReadOnly Property IsReusable() As Boolean Implements System.Web.IHttpHandler.IsReusable
        Get
            Return False
        End Get
    End Property

    Public Sub ProcessRequest(ByVal context As System.Web.HttpContext) Implements System.Web.IHttpHandler.ProcessRequest

        Try
            Dim image As Bitmap = New Bitmap(context.Request.PhysicalPath)

            Dim extension As String = Path.GetExtension(context.Request.PhysicalPath).ToLower()

            If extension = ".jpg" Then
                context.Response.ContentType = "image/jpeg"
                image.Save(context.Response.OutputStream, ImageFormat.Jpeg)
            ElseIf extension = ",gif" Then
                context.Response.ContentType = "image/gif"
                image.Save(context.Response.OutputStream, ImageFormat.Gif)
            End If
        Catch ex As Exception
            Dim message As String = "Error: " + ex.Message + vbCrLf + vbCrLf
            message += "Stack Trace: " + ex.StackTrace + vbCrLf + vbCrLf

            Dim exception As Exception = ex.InnerException
            While exception IsNot Nothing
                message += "Error: " + exception.Message + vbCrLf + vbCrLf
                message += "Stack Trace: " + exception.StackTrace + vbCrLf + vbCrLf

                exception = exception.InnerException
            End While

            Dim log As New EventLog("Application")
            log.Source = "InhouseApps"
            log.WriteEntry("This is a simple event log entry")

        End Try
    End Sub

End Class

2. Copied the .dll into c:/windows/system32/inetsrv/

3. Added a virtual directory to the web site

I named it HttpHandlerTest.

4. Added .jpg extension to web app.

Went into the properties for the web app. Under Virtual Directory/Application settings I went into Configuration. The added an extension. I selected my dll, typed in .jpg, selected All Verbs (although I think I only need GET).

5. Referenced HttpHandler in my web.config file

Code:

---

    <system.web>
        <httpHandlers>
            <add verb="*" path="*.jpg" type="ImageHandler.ImageHandler,ImageHandler" />
        </httpHandlers>

---

6. Tested it

When I tested it I don't get any jpg images returned and my code didn't add anything to the event log.

Can someone help me get this working?
Thanks,
