The DotImage controls do not include a ThumbnailViewer for WPF applications. Instead, add an AtalaImageViewer inside a repeating control programmatically, such as a StackPanel or WrapPanel, and put that inside a ScrollViewer:

(XAML)

<scrollviewer>
	<stackpanel horizontalalignment="Stretch" name="stackPanel1" verticalalignment="Stretch" canverticallyscroll="True">
</stackpanel></scrollviewer>

(Code-behind)

string filename = @"E:\demo images\usc.tif";
int frames = RegisteredDecoders.GetImageInfo(filename).FrameCount;
for (int i = 0; i < frames; i++)
{
    AtalaImageViewer aiv = new AtalaImageViewer();
    aiv.Height = 1000;
    aiv.Width = 1000;
    aiv.AutoZoom = AutoZoomMode.BestFit;
    aiv.Open(filename, i, null);
    stackPanel1.Children.Add(aiv);
}
