Featured images stopped rotating

In adding a featured image for my latest review online, it’s stopped them rotating (there’s 5 set to rotate in turn). I’m using a theme called IGames from NewWPThemes, but whenever I’ve tried to use their forum, you never get any replies.

I’ve tried changing the image, and checking the dimensions are what it normally accepts (610×320), and it still doesn’t want to know.

Does anyone have any ideas as to why it might’ve done this, please?
