Looking for your photo gallery plugin recommendations

[Barbara Schendel-Kent]

Hi all, I have a client who has a very specific photo gallery type in mind -- he wants his gallery to look and behave kind of like the below, where the gallery itself opens in a lightbox, has a big photo on top and all the smaller ones (which scroll into view left/right as needed) below it.  

See screenshot below.

Preference given to those that don't have a big learning curve for him to set up and customize. He wants it to be very intuitive for him to just go in and drag images into without having to customize it every time. 

Suggestions?
