How can I share a single NextGEN Gallery image?

Social websites fetch the meta tags from shared webpage URLs to determine the correct title, description, images, etc. The problem with the NextGEN Gallery “lightbox” effects is that overlayed lightbox images don’t have a URL, so they cannot be shared (you can only share a URL, not the overlay). To share a single NextGEN Gallery image, you have to create a Page with a [singlepic] shortcode, or select the “Show ImageBrowser” option in the Gallery settings. When using the “ImageBrowser” option, images will be displayed on their own, with a unique URL that can be shared (instead of layering the image over the webpage).
