WebClient only works once?!

[thud]

Dim myWebClient As New WebClient()
        ' Me.Text = "Downloading Image"
        Dim img As HtmlElement
        For Each img In WebBrowser1.Document.Images
            If img.OuterHtml.Contains("vacation") Then
                Dim fileName As String = "vacation.jpg"
                Dim myStringWebResource As String = Nothing
                myStringWebResource = img.GetAttribute("src")
                myWebClient.DownloadFile(myStringWebResource, fileName)
                myWebClient.CachePolicy = New RequestCachePolicy(RequestCacheLevel.NoCacheNoStore)
            End If
        Next

On each refresh in webbrowser1 the "vacation" image changes. I need it to download the new image every time.

It only downloads an image once. If I have it download again it will only download the last image which is why I thought it was caching it - not doesn't seem to be the issue because I made webclient nocache/nostore.

I launch the program - and it downloads the new image.

It will not download an image twice... It seems like it is caching the first but heh...

What's going on?

Update:

It looks like it can't overwrite vacation.jpg with the new image because its in use... I tried to do " myWebClient.Dispose()" but that doesn't fix the problem.

You'll need to look at the page again. I doubt whether vacation.jpg is the dynamic image. It may be that the img element in the page has a different src attribute each time you load the page. So it may be vacation.jpg one time, but not subsequent times.
