I've tried a number of the templates on WordPress.com and have had varying success with the view of the custom header on an iPhone. I saw a blog using Ambriu and liked the way it showed the full header image when viewed as a mobile page. I tried that template and, after a couple of tries, was able to see the header I uploaded without it being cropped. As I tried some other templates and then tried Ambriu, I have not been able to get the header image to show up uncropped. Are there special considerations for doing this. It seems to me I had to hide the text over the header to make it work the first time. Do I need to edit the CSS? Thanks.
The blog I need help with is richardvogel.wordpress.com.
