Hello ukidnme$ -
We are not aware of any issues similar to what you have described regarding the scrolling gallery, however, given the item number you have provided this may be an issue with the types of listings you have posted. Please be aware that Adult items will not appear in the scrolling gallery unless a user is signed in to an age verified eBay account and is in the Adult area of eBay - so a mix of items from different categories would only leave non-Adult items showing on non-Adult pages, but the Adult items should show correctly in the gallery on other items while in the Adult area.
The gallery appears to be operating correctly on the item number provided. If you are not seeing other similar items in the gallery when you view this item, please try clearing the cache of your browser prior to returning to eBay and if the difficulty persists please feel free to file a support case providing the details of what you are encountering so we can take a look into it. Please be sure to include your Operating System and Browser information in the case so we can test accordingly.
If you switch over to have all of your currently active listings use our new scrolling gallery, if there is only one item available, the gallery will not show at all instead of showing NULL, which can occur if, at any given time, you have only one non adult item available as the Adult items will not show in the gallery when it appears in other categories. Please feel free to file a case and request that we update your currently active items to make use of the new scrolling gallery if you wish.
