Ways to display pictures on iPad.

With its 9.7 inch, 1024-by-768 resolution, 132 pixels per inch, backlit LED display, Apple's iPad is an appealing platform for displaying photos. There is an array of apps in the iPad apps store that help do that.
The iPad itself comes with Photos app which is a tool that among others functions, helps display your pictures stored inside the iPad as well as some from elsewhere in an album fashion when you choose Album view.
A way to display photos from somewhere else as an album on iPad, is to sync the device with a feature called Smart Album from Aperture or iPhoto that collects all your best pictures. Once you do that, any time you launch the Photos app on iPad, all those photos will appear as un album if you are in album view.
There are a lot more that you can do with your photos using the iPad, like selecting pictures from a thumbnail and email them to someone or view them in a slideshow.
