Drag and Drop image from browser to WPF Application

I'm trying to implement functionality in my WPF application to drag an image out of a browser and into a window in my WPF app.

The code works fine with Firefox and Windows Explorer, but issues arise with Chrome and IE (haven't tried any other browsers just yet).

Here's a code snippet:

private void Drag_Enter(object sender, DragEventArgs e)
{
    foreach (string format in e.Data.GetFormats())
        Console.WriteLine(format);
    Console.WriteLine("Effects:" + e.AllowedEffects);
}

private void Drag_Drop(object sender, DragEventArgs e)
{
    string[] files = (string[])e.Data.GetData(DataFormats.FileDrop);
    ImageSourceConverter converter = new ImageSourceConverter();
    foreach (string file in files)
    {
        if (converter.IsValid(file))
        {
            // Do something with the image
        }
    }
 }

Looking at the output, it seems that Firefox actually saves the image to the clipboard, whereas Chrome is just grabbing the html of the image, while IE doesn't do anything with it.

Anyone have some insight as to how I may get cross-browser functionality?

Update: A couple of workarounds I've found are to parse the html (Chrome/Firefox) for an image source, then download from the source using something like the WebClient object. Would prefer a method, though, that has stronger checking for file type.

IE9 and Firefox both have a DeviceIndependentBitmap file format that is available when dragging an non-hyperlink image. This seems to be a safer alternative, though Chrome does not seem to support it. It is also not so useful with hyperlink images.

With Firefox, the output is (Drag_Enter for some reason gets fired twice):

text/x-moz-url
FileGroupDescriptor
FileGroupDescriptorW
FileContents
UniformResourceLocator
UniformResourceLocatorW
text/x-moz-url-data
text/x-moz-url-desc
text/uri-list
text/_moz_htmlcontext
text/_moz_htmlinfo
