Yes.
We've always been able to change the background images. They're in the titlesbank folder.
If you want your own backgrounds without overwriting issues then create a new folder in your titlesbank, name it how you want, then copy the contents of titlesbank\default into your new folder, you can change the images to your hearts content. Then before you create a standalone open the text document that is in the titlesbank and change the text in it from default to the name of your folder, load gameguru, load your maps and then create standalone.
