C# + WPF + WrapPanel

If someone is familiar with WPF in C#, I'd love a bit of guidance here...

My goal: Create a gallery of thumbnails within a WrapPanel, given filePaths already defined in a ListBox's Collection.

I'm not really sure how the properties of the WrapPanel control work though, since it doesn't seem to have anything like a Source property. Does anyone know how I might be able to do this?

<WrapPanel name="nig">
<Image name="nigimg1" />
<Image name="nigimg2" />
<Image name="nigimg3" />
</WrapPanel>
nigimg1.Source=GetSomeShitFromListBox(nigListBox);
