Plogger is currently set up to have 2 levels of organization: Collections and Albums. The first view you have (sexypencil.com/) is an overview of all the collections (currently you only have 1 collection with any images in it). When you click on that, this view is of all the albums within that collection (currently, you have only 1 album with any images in it -> sexypencil.com/?level=collection&id=2). One more click brings you in to the album view, which shows you thumbnails of all the images stored in that album (currently you only have 1 image within that album -> sexypencil.com/?level=album&id=2). You click a final time and it takes you to the large image (sexypencil.com/?level=picture&id=2).
Right now it's a little confusing since you only have 1 image within 1 album within 1 collection, but as you get more uploaded, it makes it easier to categorize, etc. My fix above is if you click on the large image and want to view the original uploaded image. I hope that all makes sense.
