Tempera Header on Mobile Phone

Hi Tempera Community,

Can someone kindly help advice me. I have created a header banner 1150 x 100 pixels for my website http://www.kisekiexperience.com

On the computer the image displays nicely. But when I check on my Samsung handphone, the header is distorted. It stretches to become a bigger size.

I clicked on Header Settings, Keep header image ratio. It does not work. Header image is still distorted on my handphone.

What do I need to do to ensure it stays the same?

Appreciate your advice.

Thank you 🙂
Laurent
