Yesterday Ebay was under construction and I think that's why photos aren't coming up in the gallery view.
Before I noticed, I had listed eight items. All of which weren't showing up in the gallery view. It's now been four hours and the photos are finally slowly starting to show up.
It typically takes 5 minutes or so for a photo to start showing up. So this isn't normal but it does happen once in a while.
But yeah, it's a little of a waste. I want my full 7 days. And the first few hours and the last few hours are the most important part of the auction :-)
