Thumbnail Gallery, created by Marius Donea, is one of the most configurable gallery plugins in existence. I purchased this plugin at Code Canyon and consider it money (a modest $15.00) well spent. Sure, I could have installed NextGen Gallery, added the thumb scroller plugin and had close to the same result. However, one must consider longevity. Paid for premium plugins stand a much better chance of being support/upgraded. Their authors are more likely to be available for counseling and advice and often, outright installation & configuration support.
