I want to show a gallery

I want to have a plugin that will be able to show several pictures on my blog post without making the post super long.

Is their a plugin that looks like a box and 80% of the box is filled with the first picture then underneath the picture it shows several thumbnails of the rest of the pictures?

If you don’t have that what are other good gallery plugins. I just have 50+ images and I don’t know how to display them all in one post. Can someone help me out here?
