Hi GrannyVix,
Thanks for letting us know about this. I just looked through a few of your active listings and was able to see all your active eBay listings in each that I viewed so, unless I am missing something, it appears this issue has since been resolved.
The scrolling gallery can display a maximum of 16 listings at any given time but it should display all of them any time that you have 16 or less active listings running on eBay.
If you are still in need of assistance with this, please contact our customer support team by mousing over the "Help" tab within your account and selecting the "File Support Case" option.
