Answer 1

<Button x:Name="ButtonName" Height="Auto" Width="Auto">
    <StackPanel>
          <Image Source=image.JPG" Stretch="Fill" Height="Auto" Width="Auto" />
          <TextBlock Text="picture Button" TextAlignment="Center" />
    </StackPanel>
</Button>

Thing is donot set the content property of the button. Also give appropriate size to the button otherwise image control will make it excessively big

Put your controls inside the stackpanel which can take many children instead of only one child as supported by button, and you can control the size more easily.

Based on the image you gave, here is my code. Also you should put that image link in your question

<Button  Content="Text" Height="Auto" Width="Auto" BorderThickness="0">
     <Button.Background>
          <LinearGradientBrush StartPoint="0 0" EndPoint="0 1">
               <LinearGradientBrush.GradientStops>
                   <GradientStopCollection>
                       <GradientStop Offset="0" Color="#FF03CCF0" />
                       <GradientStop Offset="1" Color="#FF0182C2" />
                   </GradientStopCollection>
               </LinearGradientBrush.GradientStops>
           </LinearGradientBrush>
      </Button.Background>
  </Button>

Change button size according to requirement. Also you may need to change the background for other visual states using VisualStateManager, but the result will be much cleaner. Also there is very dirty trick too. I am not posting code for it. use a canvas as content, set it's background and then insert a textblock inside. I don't know will this work, but I wont do it anyway. using VisualStateManager is recommended.

The cleanest way for an Image to act as a Button is to set the style property.

<Style x:Key="CustomButton" TargetType="Button">
    <Setter Property="Template" >
        <Setter.Value >
            <ControlTemplate>
                <Image Source="Images/Sample.jpg" />
            </ControlTemplate >
        </Setter.Value >
    </Setter >

Set this code in your page by defining a new block <Grid.Resources></Grid.Resources> or you could do it universally in the StandardStyles.xaml and when you're defining a new Button set the BasedOn property to the Key value that you've defined in the style.
