This layout splits the main working space into a Thumbnail panel with a grid of small thumbnails, and the Preview panel showing two small images.

This is a very similar layout, but with the Browse panel hidden. This allows more thumbnails to fit in the same size screen, while still seeing both the Thumbnail panel and the Preview panel.

This is the same layout as above, just with the panel orientation changed to portrait mode. This allows for a larger preview image when viewing portrait oriented images.

This layout is similar to the second one above, but the Thumbnail panel is now in filmstrip mode (Standard View), showing only a single row of thumbnails. The Preview panel now allows for a much larger image to be displayed.

In this layout, the Preview panel is hidden, allowing the Thumbnail panel to fill the entire screen. This is great for quickly browsing through hundreds or thousands of thumbnails.
