Question [Q] Lockscreen gallery slideshow?

So my boss' wife got a HTC One and she just upgraded to 4.3 and have now lost a feature where she was able to set a slideshow on her lock screen. As I understand this feature is not available in Sense 5.5 and I have been looking for widgets that could do this and found Photo Grid/Frame Widget, but she wants it to be fullscreen so do you guys know any simple and good lock screen that can do this task?
