wpf itemscontrol datatemplate margin

Question

不要介意左右侧边栏，它们只是暂时的，直到我做好了。

正如您在下面的代码中所看到的，以及Image I＆＃39; m在数据模板中列出我的所有艺术家（来自observablecollection）。

我的问题是：如何制作它，以便在调整gui大小时图像变大，或者添加更多边距。因为现在，在右手边没有空间（我想要的）或太多的空间。 我知道为什么会发生这种情况，新项目不够大，无法添加，所以它会在下一行添加。但我真的不知道如何在我的代码中解决这个问题。

<ItemsControl ItemsSource="{Binding}">
        <ItemsControl.DataContext>
            <CollectionViewSource Source="{Binding DataContext.Artists, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type Window}}}"/>
        </ItemsControl.DataContext>

        </ItemsControl.ItemTemplate>
    </ItemsControl>

这里应该如何
