Hi everyone, I'm hoping someone could help. I am making a photography website and need most of my product images to be set to an aspect ratio of 16:9. I was able to do this for the main store front where customers can see the thumbnails, but when I click on the individual products, the only formatting options for the page are full, half, wrap, etc. I set it to wrap. It looks ok, but it looks it is either a 4:3 ratio or just square. This won't work for photos with a wide aspect ratio. Is there a way to change the ratio of the images to 16:9 on the individual product pages. I attached a couple images to illustrate what I'm talking about. Thank you! Jeremy
