Modify User Control from Application Design?

Hi guys, I just made a simple user control (my first one) so I have close to 0 ideas about how to manipulate them.
Anyway, my user control has 3 pictureboxes with a bunch of code. What I would like to do is edit the background images of these pictureboxes when I add my control from the toolbox, but I can only click and modify the properties of the whole usercontrol, and not the pictureboxes it contains.
How would I make the pictureboxes modifiable just like the usercontrol itself?

Try creating properties for them in the UC code, something like...

Code:

---

Private _pic1BackImg As Image
Public Property pic1backImg() As Image
    Get
        Return _pic1BackImg
    End Get
    Set(ByVal value As Image)
        _pic1BackImg = value
        PictureBox1.BackgroundImage = value
    End Set
End Property

Private _pic2BackImg As Image
Public Property pic2backImg() As Image
    Get
        Return _pic2BackImg
    End Get
    Set(ByVal value As Image)
        _pic2BackImg = value
        PictureBox2.BackgroundImage = value
    End Set
End Property

EDIT Not sure you even need to set a private variable, could just try...

Code:

---

    Public Property pic1backImg() As Image
        Get
            Return PictureBox1.BackgroundImage
        End Get
        Set(ByVal value As Image)
            PictureBox1.BackgroundImage = value
        End Set
    End Property

    Public Property pic2backImg() As Image
        Get
            Return PictureBox2.BackgroundImage
        End Get
        Set(ByVal value As Image)
            PictureBox2.BackgroundImage = value
        End Set
    End Property

Thanks man, that did the job, I got the idea now.
