Hey 1-2-create,
I just checked a few of my listings and all my scrolling images are working fine.
It might be your computer/internet connection.. a delay or interruption.. If you really want to test it.. restart your computer and try logging back into eBay and look again. If it still shows that.. go to one of my listings and see if it is happening there too.
I wouldn't worry too much about it.
And yes, there are many things 'sad' about eBay's new lower fees and 'Buyer can only receive positive feedback' policy changes....
