Home: Showcase an image across the top, much like this: http://igniteflash.com/themeforest/blender/
Home page should not have a sidebar, and wallpaper images should be shown in rows and columns. I would like this to be full-width and look good from 1024x768 up to 1920x1080 and higher.
Image View: Viewing a selected wallpaper image, should show the image at the top with details below. Possibly with a sidebar on the left or right to allow for more actions.
Filtered List: Shows a subset of images, filtered by artist, rating, search query... etc. Should have a sidebar on the left or right to allow for more filtering/searching.
Please contact me if you need any clarification or need more information about any of the needed pages.
