Silverlight Image element not showing up

Question

Silverlight newbie question:

I've got a small Silverlight application with the following XAML snippet:

<Image Source="http://judahhimango.com/images/smileys/cool.gif" />

The image doesn't show up! I would expect the image to download asynchronously, then show up in the UI, but alas, no such luck.

What am I doing wrong?

Update -------------------------------------------------

Ok, no-go on the .GIFs, forgot about that. But using a PNG doens't work either:

<Image Source="http://judahhimango.com/images/smileys/cool.png" />

However, if I change the Source to a BitmapImage, then it works:

<Image>
      <Image.Source>
         <BitmapImage UriSource="http://judahhimango.com/images/smileys/cool.png" />
      </Image.Source>
</Image>

Why can't I just specify the Image Source? Why do I have to specify a BitmapImage?

I think SL does not support gifs: http://forums.silverlight.net/forums/p/3883/232781.aspx can you try a jpg?

<UserControl x:Class="SilverlightApplication2.MainPage"

</UserControl>

3/9/10: OK, I think I know what your problem may be. When you create a new silverlight application project in Visual Studio, it gives you the option of hosting it in an ASP.NET website. Did you select that option? If not, please select it, and give it a try. See this: http://stackoverflow.com/questions/1053081/deep-zoom-is-not-displayed/2413697#2413697
