save images in webbrowser control without redownloading them from the internet

Question

Is it possible to save images in a webbroswer control directly to hard disk, without needing to download them again from the internet?

Let's say I navigate to a website that has 15 images. They are all viewed in my webbrowser, but how can I save them now without the need to download them?

Answer 1

This is the only way I could find. Curious if anyone else has a better way.

You have to add a reference to Microsoft.mshtml and of course wait for the document to finish loading. This will save the images loaded in a System.Windows.Forms.WebBrowser webBrowser1 component - even the ones you don't want.

IHTMLDocument2 doc = (IHTMLDocument2) webBrowser1.Document.DomDocument;
IHTMLControlRange imgRange = (IHTMLControlRange) ((HTMLBody) doc.body).createControlRange();

foreach (IHTMLImgElement img in doc.images)
{
  imgRange.add((IHTMLControlElement) img);

  imgRange.execCommand("Copy", false, null);

  using (Bitmap bmp = (Bitmap) Clipboard.GetDataObject().GetData(DataFormats.Bitmap))
  {
    bmp.Save(@"C:\"+img.nameProp);
  }
}
