I don’t know if anyone has thought of this yet ( i am sure someone has) but I am planning on using this module to also sell an upgraded advertising position on my site. Rather than just a plain banner ad, I think you could upgrade an ad position and charge a little bit more using the functionality of this module with the picture in the background and then the scroll effect to upsell to potential advertisers.
You can actually make these images different sizes and place them not only in user 1, 2, 5 positions but also in the left and right positions as well as position 5. So then you can offer advertisers a standard banner or this option with spotlight.
Just an idea that I thought I would share with the forum.
