I tried my Lightflow Album on my iPad Mini and it works without an issue in both vertical and horizontal formats. The bottom scroll bar can be difficult to use because of its size but this is a minor issue as it doesn't prevent me from scrolling through the photos. However, an office mate said she had trouble. I was testing in Safari iOS 7.
Is your album embedded on a website or is it a jAlbum hosted gallery? I had an issue similar to this but it was my site causing the problem not the Lightflow gallery. Once I corrected my site all was fine.
I have the same issue that cehu had in the message of 16/1/2014. I am using jAlbum 12.3.5, Lightflow 3.8.7.
Using an iPad2 the display is fine in Portrate but in Landscape I am losing part of the screen. Was this issue ever resolved? This happens on both the carousel display and when an individual picture is selected
