Here is the code I use in eXtreme's group window for archetypes;

    <Namespace Name="ClassStyles">
        <ImageStyle Name="Warrior">
            <ImageFrame Source="/images/widgets01.dds" SourceRect="217,4,249,34" />
        </ImageStyle>
        <ImageStyle Name="Mage">
            <ImageFrame Source="/images/widgets01.dds" SourceRect="215,83,249,118" />
        </ImageStyle>
        <ImageStyle Name="Priest">
            <ImageFrame Source="/images/widgets01.dds" SourceRect="217,43,249,74" />
        </ImageStyle>
        <ImageStyle Name="Scout">
            <ImageFrame Source="/images/widgets01.dds" SourceRect="216,125,248,156" />
        </ImageStyle>
    </Namespace>

And just in case you want or someone else wants, here is the code I use for player's class in the player window.
