new format to see the photos, there is no more full screem or how can you make full screem?Does anyone like the new format?

While I do not see the same thing you do on listings, YES fill out the feedback form. Ebay is using that to help make their decision on what format to make site wide. For me, I can still click on a sellers pic and get to the larger pics. What you are seeing is real, but just a test, annoying as it may be. Hopefully it will go away in a few days or week for you.
