Using the back and next arrows is probably the most convenient way to navigate images on any site. Just open up any thumb nail view, click on an image and use the arrows to step back and forward. You can even use the arrows on your keyboard! It's now possible to use the arrows in critique, tutorials, group galleries and weekly theme and it will always show you the correct photos! Not the least we have increased the performance of the code for stepping between images 4 times!
