Organize images into groups?

Hello I am looking for a alternative to the Next Gen Gallery Plugin. For some reason it wont work on one of my websites hosting. Now I am using shutter reload for the java script popup, but I cant find a way to organize images into galleries like Next gen did. I setup an example of what I want to achieve without nextgen at this time. https://crocostrich.com/?page_id=3
