Hi stephenszoo,
When you list items directly through eBay, it typically takes about 4-6 hours for them to be imported into your Auctiva account and appended with the scrolling gallery. Therefore, since you posted this message a couple days ago, the scrolling gallery should have already been appended to the listings you are referring to.
Any additional questions or concerns? Please file a support request using the appropriate link on our help page:
