The new gallery shows four images with a small white line below the images with a series of numbers under that white line showing all the pages below the line to the right hand side. The count starts at one but can handle 10's of pages.
This flexibility is great because you can go to any level in the photo gallery to pick out something specific for which you are interested.
You may go for any image by simply using the numbers under the text until you find what you need.
In addition, if you want to get a full size image of anything in the gallery, simply click on the image and it will open a popup with the full size image. There are no cheesy navigation buttons just an "X" in the upper right corner. When you're done viewing the large image, just click the X in the upper right corner and it will take you back to the main gallery.
