Hi deviltronics,
Your missing images have been created and are now avialable in your Auctiva store: http://www.auctiva.com/stores/viewstoreitems.aspx?id=176137 . These images will also be cisible in your store window the next time it refreshes, which it does about every 2 hours.
If you notice that this happens again, please don't hesitate to file a support case and our friendly support staff will assist you.
