WordPress Gallery Object is a great gallery plugin. You can customize it almost as you like  without having to know any code language. All you have to do is to download and activate the plugin. Then you go to the gallery customization page andy put in the values you would like such as colors, size and font family. Then you get a generated code to put on your side where you would like it to appear. The gallery can be implemented anywhere, form pages to posts and also the sidebar.
