In the above getImages() method, why there is three dots. What is it mean? I searched google but couldn't find anything.

Yeah, punctuation is hard to search for if you don't know the technical term. In this case, it is varargs. Here is a nice link to explain it. Basically, the caller can add as many arguments as desired, and the method sees them arriving as an array of that length.
