In the first screenshot you see a page which list all the albums from a Picasa account. I just wrote in that page [altpwa user=...]
In this second screenshot, you can see just one album, after I click on that album in the list you've seen it above. But I can easily embed only one album if I want, using [altpwa user=... album=...]
Now it's time to see the photos. If the design is thin, maybe you will prefer to use Lightbox.
But there is always the option to have the picture inside the page, as above.
And finally, take a look at the administration page. There are several useful option here.
