In order to remove the scrolling gallery from any current listings in which it is present, you will need to delete the scrolling gallery HTML from the description HTML of each listing using eBay's "Revise your Item" form. The specific code you would need to remove begins and ends with <!--ASW-->. If you would like to see the entirety of the scrolling gallery HTML code, it can be viewed within your account by clicking the "Scrolling Gallery HTML" link under the "Store" tab.
