I have added to my original post. I like to test suggestions before I offer them. But I have not been able to do that this time. Have fun. Let us know if it works and how to fix any issues you come up with.
To create our own slide shows we need to create a folder in /usr/share/backgrounds and in that new folder we put a modified xml script following the pattern of quantal.xml. We can put our images in /usr/share/backgrounds or, for neatness in /usr/share/backgrounds/newslidshowfolder. We need to make sure that the links are pointing to the right place. Has the right path.
either
or<from>/usr/share/backgrounds/NewImage.jpg</from>
<to>/usr/share/backgrounds/NextNewImage.jpg</to>
depending upon the exact place that we put our collection of new slideshow images.<from>/usr/share/backgrounds/newslideshowfolder/NewImage.jpg</from>
<to>/usr/share/backgrounds/newslideshowfolder/NextNewImage.jpg</to>
Regards.
