You need to use a Trigger on the IsMouseOver property to modify the Source of the Image:
您需要在 IsMouseOver 属性上使用触发器来修改图像的来源：
<Image>
<Image.Style>
<Style TargetType="{x:Type Image}">
<Setter Property="Source" Value="C:\Image1.jpg"/>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Source" Value="C:\Image2.jpg"/>
</Trigger>
</Style.Triggers>
</Style>
</Image.Style>
</Image>
Note that Triggers can only be used inside Styles, and in order for a Trigger to change a property that property's value must be set by the Style and not set explicitly on the element.
请注意，触发器只能在样式内使用，并且为了让触发器更改属性，该属性的值必须由样式设置，而不是在元素上显式设置。

<Image Stretch="Fill" >
<Image.Style>
<Style>
<Setter Property="Image.Source" Value="original.png" />
<Style.Triggers>
<Trigger Property="Image.IsMouseOver" Value="True">
<Setter Property="Image.Source" Value="mouseover.png" />
</Trigger>
</Style.Triggers>
</Style>
</Image.Style>
</Image>
There are other ways that trigger. All right?
还有其他触发方式。好的？
