Resize backdrop at Frame Start?

[Renderious]

I'm trying to re-size my backdrop at the start of the frame. I notice the backdrop objects don't have any conditions so I assume I'd have to use some sort of picture object. Right now my application re-sizes the window to the screen size at start. I have a backdrop image that is 1000px by 1000px. I need this image to wrap horizontally and vertically to fill the screen. I've tried using layers but the layer size is dictated by the frame size which obviously becomes bigger than the backdrop at run time so it just displays the backdrop in the top left corner and leaves the rest of the screen blank.

I guess I am asking if there is a way to change the dimensions of a picture at run time that will wrap the image instead of just stretching it.

I wish the quick backdrop object had conditions as this would solve my issue perfectly. As of now my current fix is setting the backdrop images size to the biggest possible screen resolution so it always fills the screen. This is quite ugly however.

Thanks =)

You can make an active object instead of a backdrop, then at runtime:

Start of frame:
-> Object - (Manipulate object)
-> Object - Animation - Paste image into background - (set parameters)
-> Object - Destroy
