One of the benefits of upgrading that I’m excited about is being able to use a lightbox effect for all my images. I’m using a conjunction of the slimbox plugin and the wpg2 plugin to insert the gallery pictures with the least amount of trouble on my part. 
And the effect is really cool, but you have to have JavaScript enabled in your browser to see it. (Most current browsers enable JavaScript by default. )
To see the effect in action, click on the random image in the side bar. Now, isn’t that nice!?
