Behold the following XAML:

<Grid>
<HyperlinkButton x:Name="Link" Background="Green">
    <Grid Background="Red">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto" />
            <ColumnDefinition />
        </Grid.ColumnDefinitions>
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto" />
            <RowDefinition Height="12" />
        </Grid.RowDefinitions>
        <Image x:Name="AvatarImage" Style="{StaticResource AvatarStyle}" Grid.Column="0" Grid.Row="0" />
        <StackPanel Grid.Column="1" HorizontalAlignment="Stretch">
            <TextBlock Text="New Topic" Style="{StaticResource ItemTypeStyle}" />
            <TextBlock x:Name="Title" Style="{StaticResource HeadlineStyle}" TextWrapping="Wrap" />
            <TextBlock x:Name="SubText" Style="{StaticResource TextStyle}" TextWrapping="Wrap" />
        </StackPanel>
        <TextBlock x:Name="TimeStampText" Grid.ColumnSpan="2" Grid.Row="1" Style="{StaticResource TimeStampStyle}" />
    </Grid>
</HyperlinkButton>

In the user control’s Loaded event, I call the following code:

var imageUrl = new Uri("http://coasterbuzz.com/Forums/UserAvatar.ashx?id=2");
AvatarImage.Source = new BitmapImage(imageUrl);

Looking at Firebug, the image is coming down the wire, but for some reason it’s not displayed. Any guesses as to why? You’d probably like to see the styles, but note that if I remove the styles, nothing changes.

    Ah, easy answer. Silverlight 2 doesn’t support GIF.

    There is a handful of solutions to convert the image serverside here: http://silverlight.net/forums/t/3883.aspx

    The most official reason I can find:

    Why the support for displaying a .gif
    image is is missing? When it will be
    added?

    We don’t want to take the hit for
    another codec. It may only be a little
    bit of download time—but our mandate
    is small and fast and every little bit
    counts. We are also hesitant to
    support .gif because it implies
    support for animated .gif, which we
    decided would have to be integrated
    into our animation scheme somehow—and
    that will be a lot of work.

    Looking from Flash perspective, Flash
    does not support .gif either. However,
    as of present, this is something being
    evaluated, but no date has been
    announced
