How to set border background imagebrush in code-behind

I have a WPF custom user control that is used in a Windows Application. The control has a border as the main element, and this border has a default background image. The code below shows how this image is set as a default. The default image is a resource element (Images/BlueRoad.jpg).

I want to be able to programmatically change the image of the border background using an image filename as string (e.g. "C:\Pictures\myCustomPic.bmp"). I need to do this in code-behind using Visual Basic, unless there is a VERY simple way to do it in XAML. Either way, the picture will load in the startup code for the control.

I do not know much about WPF and this is just a small element of the application, so want to get this done as simply and quickly as possible.

Many Thanks!

<Border Name="mainBorder" Opacity="1" BorderBrush="SteelBlue" BorderThickness="3">
    <Border.Background>
        <ImageBrush  ImageSource="Images/BlueRoad.jpg"></ImageBrush>
    </Border.Background>

     Grid and other stuff goes here...

 </Border>

var imagePath = @"pack://application:,,,/MyProject;component/Resources/BorderImage.png";
ImageBrush brush = new ImageBrush(new BitmapImage(new Uri(imagePath, UriKind.Absolute)));

you can use ImageBrush and BitmapImage to set brush to border background first you create BitmapImage with uri and send this BitmapImage to ImageBrush and assign ImageBrush to border background
