Disable landscape orientations on iPhone, since it seems landscape support is not planned for iPhone.

Will this disable landscape orientation on iphone when viewing an image?

@stepheneb That's a good point, it would disable landscape when viewing an image. I hadn't considered that, but that would probably be a better experience than disabling rotation on iPhone altogether.

There are many times when viewing a screenshot someone has shared I need to both switch to landscape and zoom in so see details, Am running on a iphone with a smaller screen.

One other use I have made of landscape mode. When someone includes a url in their post that provides andimage -- and the image has detail that is hard to make out and I'd like to read more of the image before deciding to open the url I rotate the phone to see the image better. I find my self often wanting to just tap on the image to view an expanded view without rotating but a regular tap of course opens the url. Maybe something like "Open Image" could be added to the long tap contextual menu.
