Save webbrowser's images to file

[arsmakman]

Hello all,

Most programmers hate to read, so first, here is the short version of my question:

Is there a method like WebBrowser1.Document.Image(0).SaveImageToFile("C:\Image.jpg") ?

If you have no direct solution, but are willing to help me (how very kind of you ), please read on...

I'm trying to make an application that downloads all the images from a photo album on the web. The user will navigate to the first image in the gallery and the program should download all images in full resolution automatically.

I have a working version now, but it is not satisfactory. Here is a simplified version of the code I use now for saving the images:

Private Sub startDownloading Handles WebBrowser1.DocumentCompleted

My.Computer.Network.DownloadFile(WebBrowser1.Document.Images(0).GetAttribute("src"), "C:\image.jpg")

End Sub

This way, after the page with the image has fully loaded, it downloads the image using the Network.DownloadFile-method. So, it download the same file twice. But these files are big and websites are slow. Which makes the whole operation take about twice as long as it has to.

Is there a way to directly save the image-file that has already loaded in the WebBrowser-control, without having to download the image again?

Thanks for any help,
Alexander.

P.S. The images have semi-random names, so there's no automation possible there.

Is it really necessary to use the WebBrowser Control? Why not just access and save them directly?

Maybe this will work? I think it does, but you should be able to tell if it cuts your download times down for saving the images.

    Private Sub startDownloading() Handles WebBrowser1.DocumentCompleted
        'USE WEBCLIENT
        Dim wc As New Net.WebClient
        Try
            'SET CACHE POLICY TO LOCAL CACHE ONLY
            wc.CachePolicy = New Net.Cache.RequestCachePolicy(Net.Cache.RequestCacheLevel.CacheOnly)
            'DOWNLOAD IMAGE, SHOULD BE COMING FROM LOCAL CACHE
            wc.DownloadFile(WebBrowser1.Document.Images(0).GetAttribute("src"), "C:\image.jpg")
        Catch ex As Net.WebException
            'IMAGE IS NOT IN LOCAL CACHE
        Catch ex As Exception
            'OTHER ERROR
        Finally
            wc.Dispose()
        End Try
    End Sub
