Just looking to move our albums to Tiger as was really keen for shopping cart function on smartphones. Having done a test album the images are simply not showing up when clicking on a thumbnail, it moves to a black screen. (control bar still at top though).
No control bar? Perhaps you are looking at the "mobile replacement version"? You can turn this "feature" off on your jalbum.net / albums page (move the mouse over the thumbnail) -> Edit album -> Disable the automatic mobile replacement version = ON.
Uh, the "mouse wheel navigation"? Can it be that your mobile tries to mimic the mouse wheel action someway? I haven't seen such from a mobile so far.
The hero image is simply centered on a mobile. As the aspect ratio is greatly different from the desktop version. It can't be fit into the box, otherwise the image would simply be placed in the box with empty spaces below and above.
There's no such option yet as disabling the share functionality selectively in the lightbox, but I think I can add this easily.
