WPF/C#: Creating a button style: Text + Image

I just want to ask how should I put my image (dynamically) in this following code:

<Style x:Key="ButtonStyler" TargetType="{x:Type Button}">
    <Setter Property="Background">
        <Setter.Value>
            <RadialGradientBrush>
                <RadialGradientBrush.GradientStops>
                    <GradientStopCollection>
                        <GradientStop Color="black" Offset="0" />
                        <GradientStop Color="black" Offset="1" />
                    </GradientStopCollection>
                </RadialGradientBrush.GradientStops>
            </RadialGradientBrush>
        </Setter.Value>
    </Setter>
    <Setter Property="Height" Value="40" />
    <Setter Property="Foreground" Value="white" />
    <Setter Property="Grid.Row" Value="2" />
    <Setter Property="Grid.Column" Value="3" />
    <Setter Property="Content" Value="Forgot your password?" />
    <Setter Property="ContentTemplate"
            Value="{DynamicResource myContentTemplate}" />
    <Setter Property="Margin" Value="3" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <Grid>

I am planning to set the image's file destination in my code-behind (C#). For the output, the WPF button can both display the text and the image (placed in the right side of the text)

Any suggestions?

Your template includes a ContentPresenter, bound to the Content of the Button. So, you can simply set the image and/or text as the content of the button and they will go there.

<Button Style="{StaticResource ButtonStyler}">
    <StackPanel Orientation="Horizontal">
        <Image Source="..." />
        <TextBlock Text="..." />
    </StackPanel>
</Button>

just try this link. In this they created custom implementation of the button and a dependency property ImageSource so the you can use either from the code behind or from the XAML
