Picture gallery slideshow has been replaced with another one that is a lot more mobile friendly. It is now possible to use gestures to move between pictures in a post, as well as keyboard cursor keys for those using computers. Sliding up or down will close the slideshow if using a mobile.
I've just noticed that some of the elements are missing if slideshow is accessed using mobile Opera browser. I would appreciate if you could upload screenshots of an open gallery from your mobile devices so I can make sure it looks as intended (I only have access to limited number of mobile devices).
Reports of any problems are appreciated. Hope you find it more user friendly
