Looking for a simple image gallery in post plugin

Hi,
I’ve been looking at a lot of different kinds of image gallery plugins and cannot seem to find the right one. Most are either too fancy, or too complicated to implement. Or they are too simple or do not achieve the effect I need.

Here is a screenshot of what I would like. Basically a row of images along the bottom of a post, when you click one it expands to a larger size without leaving the page. Adding it to the post would hopefully be very straightforward. If anyone can recommend something they know of I would really appreciate it. Thank you.
