Hi urbano,
The scrolling gallery is set to display 14 of your active listings at a time and is refreshed every 4 hours. Each time the store window refreshes, it is populated with another 14 of your current listings that are ending around the same time as the next auction of yours that is viewed.
The only way you can currently control what is displayed in your scrolling gallery is by making items hidden, an option which you can find by clicking the “Store Items” link under the “Store” tab within your account. Any listings that are made hidden will no longer be displayed in your Auctiva store, nor will they be displayed in your scrolling gallery the next time it refreshes, which it does about every 4 hours.
Any additional questions? Pleae file a support request using the appropriate link on our help page:
