Thanks for the quick reply.
I should have mentioned I am using iOS7 on the iPhone.
The landscape viewing issue occurs when rotating, but reloading has mixed results.
On the gallery index page, landscape works perfectly. Rotating from vertical to landscape and back is seamless.
When a gallery thumbnail is tapped and "View Gallery" appears, rotating to landscape causes the thumbnail to be cropped at the bottom, and when rotating back to vertical, the cropped thumbnail remains.
When loading the site fresh in landscape view, the gallery index view is fine, but the gallery thumbnail is again cropped on the "View Gallery" page. (I'm not convinced the "View Gallery" page is even needed. It's not used on the desktop version...) if the site has been loaded from landscape initially, main image pages can be freely rotated from vertical to landscape and back, with one glitch*.
When tapping the "View Gallery" thumbnail, in a fresh loaded landscape view, the main images load somewhat properly, i.e. not zoomed in, but iOS7 introduces a dynamic nav bar at the bottom of the page which auto hides on vertical scroll.
*Because the showkase page is vertically static for mobile, the bottom toolbar in Safari doesn't hide itself, and the bottom of all main images are cut off in landscape mode, regardless of how or when the page is loaded.

This is the view when rotated from vertical.

This is the view when landscape is loaded natively, not rotated from vertical...the nav bar is cutting off the dog's legs.

This is the gallery thumbnail view in landscape and after being rotated to vertical...

I forgot to mention previously that swiping full images forward/back on the iPad (on iOS6) is somewhat laggy and not very smooth. I am using fade transitions. Tapping the nav buttons is very smooth, but swiping is delayed and jittery.
