Upload & Sell: On
I implemented a Lightbox for displaying images in the forums. Basically if you click on an image you will see it in full screen and if there are more than one image per page, you will see them in a gallery style.
You may navigate through individual or multiple images by using the 'close', 'previous' or 'next' buttons or the keyboard keys: close (ESC), previous (Left arrow) or next (Right arrow).
I hope you like it.
Here is an example thread from the Landscape Photographer board. Click on an image to see the Lightbox:
