Steven, et al.:
I have many old, stand-alone (i.e., not embedded), galleries. These have had their jbcore sub-directories updated as new Juicebox (Pro) releases have been issued.
On my iPhone6, recently updated to iOS9, I was just looking at one of them: http://www.billanddot.com/crossing-signs/index.html . On my PC (Windows Vista Home Premium SP2 32-bit, Firefox 40.0.3) it looks fine.
On the iPhone, there seems to be centering and cropping of the image when in vertical mode, and centering and cropping of the thumbnail page in both vertical and horizontal mode. I have uploaded four screen grabs of this situation:

I can't say for certain that this is an iOS9 problem, because I haven't looked at that gallery on my iPhone in a while, certainly not since some interim iOS8 releases.
On the other hand, recently created or updated galleries (and all with virtually identical configuration options) seem to work fine on the iPhone. My most recently created gallery, for instance, is this one: http://www.billanddot.com/2015-08-25-No … Track-Day/ .
And of course I have cleared Safari's cache before doing this experimentation on the iPhone.
I'd appreciate any thoughts you may have on this.
Thanks,
Bill P.
