I'm trying to make a gallery for some of my photoshop stuff, and I'm almost positive what I want to achieve can be done through Ajax.

Look at this website: https://www.worldofwarcraft.com/downloads/ssotd/

see how when you click on a thumbnail, it makes a new window and resizes itself, with some buttons in the corner. Does anyone know how to do this? Is it even Ajax?

Thank you for any help you can give.
