Adding a background image using CUI?

Hi, I am 100% noob with the CUI.

I have this;

Code:

[...]{
                    new CuiPanel
                    {
                        Image = { Color = "1 1 1 1" },
                        RectTransform = {AnchorMin = "0 0", AnchorMax = "1 1"},
                        CursorEnabled = true
                    },
                    new CuiElement().Parent,
                    ShopOverlayName
                },
[...]

And I want to know if can I add background image to that.

Thank you.
