I had to update my K2 in order to be able to put links on the entire image in the slider.
So I upgraded from 2.5.7 to 2.6.5. After this most of the modules under K2 in Extension Manager are of version 2.6.5. But K2 Camera Slideshow is still 2.5.7.
How can I upgrade just that one? And why was it noe upgraded when I ran the entire package?

that doesnt sound like a default k2 module...
