Excellent wordpress web gallery software

Been using the NextGEN gallery plugin for over six years. Easy to use, and offers a variety of elegant photo galley display options from blog rolls, to slideshows and mosaic layouts. Behind the scenes the back end photo management system allows for easy bulk uploads, seo tagging, watermarking and thumbnail creation to name a few of the options available. The addition in the last few years of the ecommerce option to provide multiple price menu options, and recently coupons is welcomed and integrates seamlessly to provide clients with the ability to buy pictures, digital downloads and products from directly from within their galleries. Would like to see further ecommerce features in the near future to allow creation of packages or collections, limiting the amount of poses that can be selected for the collection, minimum spend, compare side by side, buy all, and a wall designer option to add framed products around chosen images. Email support is also excellent. Thanks for a great product and keep up the good work.
